EXHIBIT 99.1

Harsco Corporation Reports Second Quarter 2011 Diluted Earnings Per Share From Continuing Operations of $0.47 vs. $0.40 in the Second Quarter Last Year

Revenues Up 11 Percent to $875 Million

HARRISBURG, Pa., July 28, 2011 (GLOBE NEWSWIRE) -- Worldwide industrial solutions company Harsco Corporation (NYSE:HSC) today reported second quarter 2011 results from continuing operations.

Second Quarter 2011 Highlights

Second quarter 2011 diluted earnings per share from continuing operations were $0.47, compared with $0.40 per share in the second quarter of last year. Income from continuing operations was $39.2 million, compared with $34.3 million in the second quarter last year. Sales increased by 11 percent in the quarter to $875 million, from $787 million in last year's second quarter. Foreign currency translation increased sales by approximately $62 million and operating income by approximately $2.7 million, when compared with the second quarter of last year.

For the first six months of 2011, diluted earnings per share from continuing operations were $0.62, compared with $0.50 per share in the first half of 2010. Income from continuing operations was $52.8 million, compared with $44.0 million in the first half of last year. Sales increased by 8 percent in the first half of 2011 to $1.7 billion, from $1.5 billion in last year's first half. Foreign currency translation increased sales by approximately $80 million and increased operating income by approximately $2.8 million, when compared with the first six months of 2010.

Comment

Commenting on the Company's results, Harsco Chairman, President and Chief Executive Officer Salvatore D. Fazzolari said, "We continue to be pleased with the overall performance of our operations. In addition to achieving results above the upper end of our previous guidance for the second quarter of this year, the quarter also benefited by $8 million ($0.07 per diluted share) from the reduction of estimated costs related to the first phase of our large equipment order to the Ministry of Railways of China.

"While we experienced some headwinds in the quarter within our Harsco Metals & Minerals Segment from lower stainless steel production at mills served, as well as lower stainless steel scrap pricing, both of which negatively affected margins, overall revenue growth was achieved and new contract bidding activity remains strong.

"Within our Harsco Infrastructure Segment, we are clearly achieving the substantial cost savings that we had anticipated as a result of our fourth quarter 2010 restructuring actions. While certain end-market challenges remain, particularly in the United Kingdom, the operating loss in the quarter was substantially reduced, both year-over-year and sequentially from the first quarter of the current year.

"Both our Harsco Rail and Harsco Industrial Segments continue to perform well as we expand both businesses across the globe.

"While we are encouraged by our results in the second quarter and the first half of 2011, it remains prudent for us to continue to view the near-term outlook with a degree of caution, particularly due to certain global market uncertainties. Nevertheless, we are for the second time this year raising our full-year 2011 earnings guidance by $0.05, from $1.30 to $1.40 diluted earnings per share from continuing operations to a new range of $1.35 to $1.45.

"This increased guidance for 2011 is based on the following factors. On the positive side, the expected full-year results factor in the lower cost of sales benefit from Harsco Rail that was realized in the second quarter as well as an anticipated lower effective tax rate for the second half of the year. The following factors were also considered in developing guidance: the impact of lower stainless steel scrap pricing in the Metals & Minerals Segment for both the second quarter and the remainder of the year; higher due diligence costs as we continue to review acquisition opportunities; a further deterioration of the United Kingdom economy and construction market affecting the Infrastructure Segment; and the timing of a Rail machine sale for China that has been re-staged for delivery from late in the fourth quarter of this year to early in the first quarter of 2012.

"Our present outlook for third quarter 2011 earnings from continuing operations is in the range of $0.37 to $0.42 per share, which compares with $0.26 per share in the third quarter of 2010."

Second Quarter Business Review

Harsco Metals & Minerals

Sales in the second quarter increased approximately $48 million to $424 million, up 13 percent from $376 million in last year's comparable quarter. Foreign currency translation increased sales in the quarter by approximately $34 million, and operating income by approximately $3.3 million. Operating income in the quarter decreased by $5.4 million to $35.3 million or 13 percent from last year's operating income of $40.7 million. Likewise, operating margins of 8.3 percent in the quarter were lower than the 10.8 percent in the second quarter of 2010. Last year's second quarter included a net asset gain of approximately $3.0 million that was not repeated in this year's second quarter, resulting in lower operating margins on a comparative basis by approximately 70 basis points. Furthermore, operating income and margins in this year's second quarter were both negatively affected by reduced commodity prices in the minerals and recycling technologies product group. The Company's on-site services to metal producers performed well in the quarter.

The outlook for this Segment remains favorable, with the expectation of further new contract signings in the second half of 2011 and a continuation of strong bidding activity longer-term. Looking ahead specifically to the second half of 2011, the Company expects lower stainless steel scrap pricing to negatively affect the minerals and recycling technologies product group, but this should be offset by continued favorable performance in the on-site services to metal producers. Overall this Segment is expected to show year-over-year improvement for the second half of 2011.

Harsco Infrastructure

Sales in the second quarter increased approximately 14 percent to $298 million, from $263 million in the second quarter of last year. Foreign currency translation increased sales by approximately $26 million in the quarter when compared with the second quarter of 2010, but had a negative effect on operating income in the quarter of approximately $0.9 million. An operating loss of $5.1 million was incurred in the quarter, compared with an operating loss of $13.6 million in the second quarter of last year and an operating loss of $17.5 million in the first quarter of this year. 

As expected, this Segment is beginning to realize the forecasted savings from the successful implementation of the major restructuring plan announced at the end of 2010. The Company continues to expect such savings will approximate $40 million in 2011, with full annualized savings of $60 million starting in 2012. While average rental rates and utilization rates have stabilized in recent quarters, uncertainties remain in key end markets, particularly in the United Kingdom, several other European countries and, to a lesser degree, the United States.

The outlook for this Segment continues to be underpinned by the expected restructuring savings. This Segment should continue to show sequential improvement from the second quarter but is still expected to post operating losses in the third and fourth quarters. Longer-term, the full annualized cost savings of approximately $60 million starting next year should position the business to achieve break-even or better in 2012.

Harsco Rail

As expected, sales in the second quarter of 2011 decreased to $78 million, down approximately 10 percent from sales of $86 million in last year's second quarter. However, operating income in the quarter increased to $22.5 million, from $21.6 million in the comparable quarter of last year. Income in the quarter benefited by $8 million pre-tax due to a change in estimated costs related to the first phase of the China Ministry of Railways equipment order. 

Excluding this $8 million item, operating margins in the second quarter of 2011 were 18.6 percent, compared with 25.0 percent in the second quarter of last year. Sales, income and margins in last year's second quarter benefited from the timing of equipment deliveries, which as previously discussed were heavily weighted in the second quarter and first half of 2010.

The outlook for this Segment continues to be favorable, and results in the second half should exceed last year's second half. However, this year's second half results will be impacted by the timing of a major machine sale to China which had been expected to be delivered late in the fourth quarter of 2011, but is now expected to be delivered early in the first quarter of 2012. The longer-term outlook for the Segment remains favorable. The global demand for railway maintenance-of-way equipment, parts and services continues to be strong. Closer to home, the Class I railroads in the United States continue to report improved earnings and increased freight shipments, a positive indication of further opportunities for the Rail business going into 2012.

Harsco Industrial

Sales in the quarter increased approximately 22 percent to $75 million, from last year's second quarter sales of $61 million. Operating income in the second quarter was $13.0 million, compared with operating income of $13.7 million last year. Operating margins in the quarter were 17.4 percent, lower than operating margins of 22.4 percent in last year's second quarter. The decline in operating income and margins in the quarter was the result of product mix and to a lesser extent higher LIFO costs.

The outlook for this Segment continues to be favorable as the business expands across the globe and bidding activity is very strong. The second half 2011 performance is expected to slightly improve over last year's comparable period.

Liquidity, Capital Resources and Other Matters

Net cash provided by operating activities for the first half of 2011 was $66.9 million, compared with $125.7 million for the prior year. The decline in cash from operations is due principally to higher working capital from increased sales and timing of cash receipts. Over $40 million in cash was collected during the first few days of July that had been forecasted for receipt in late June. Also, working capital was adversely affected by $15 million in cash used for the fourth quarter 2010 restructuring of Harsco Infrastructure. As in prior years, the Company expects that the preponderance of cash flow from operations will be realized in the second half, particularly the fourth quarter.

Net cash used by investing activities was $129.7 million, compared with $84.2 million in the first half of 2010. The increase in capital expenditures is due to contract renewals and new contract signings, principally in the Metals & Minerals Segment, where bidding activity remains strong. 

The total debt to capital ratio at June 30, 2011 was 38.0 percent, unchanged from March 31, 2011 and slightly higher than the 37.6 percent ratio at December 31, 2010, which was the Company's lowest level since 1998. Total debt outstanding stood at $948.5 million as of June 30, 2011, compared with $884.9 million at the end of 2010.

Economic Value Added (EVA^®) improved in the second quarter and first half of 2011 over the comparable periods in 2010, due principally to higher earnings and to a lesser extent lower capital employed.
