Line 397:

Mallinckrodt established a uranium metal plant on the second floor of the building containing the green salt plant using the Ames Process. Production commenced in July 1943 and {{convert|1,364|ST|t|order=flip}} of metal was produced by 1 January 1947, at a cost of $2,773,750 ({{Inflation|US|2,773,750|1947|fmt=eq}}). The unit price contracted for the first {{convert|90|ST|t|order=flip}} was $4.17 a pound, but Mallinckrodt found that it could produce it for substantially less, and voluntarily refunded $2.20 a pound to the government. By 1 January 1947, the price had fallen to $0.71 per pound.{{sfn|Manhattan District|1947a|pp=10.2–10.3}}

The Electro-Metallurgical Company in [[Niagara Falls, New York]], (a division of [[Union Carbide]]) built an Ames Process uranium metal plant on its property under a cost-plus-fixed-fee contract at a cost of $234,300 ({{Inflation|US|234,300|1943|fmt=eq}}). The plant operated from April 1943 to Ju1yJuly 1946, and produced {{convert|1,538|ST|t|order=flip}} of metal at an average cost of $0.67 per pound.{{sfn|Manhattan District|1947a|pp=10.3–10.4}} DuPont built a plant in Deepwater for $1,050,300 ({{Inflation|US|1,050,000|1943|fmt=eq}}). The plant encountered various difficulties in operation and only produced {{convert|232|ST|t|order=flip}} of metal at an average cost of $1.72 per pound before the Manhattan Project decided to close it down in August 1944.{{sfn|Manhattan District|1947a|pp=10.3–10.4}}
