摘要： Platinum group metals, gold and silver are extracted from complex ores, automobile scrap, refractory ores and as naturally occurring by leaching the precious metal containing materials with a solution containing halogen salts such as potassium or sodium iodide and bromide in the presence of ammonium ions and oxygen. The precious metal containing materials and reactants are charged into a reaction zone held at high temperatures and pressures to form a slurry containing a precious metal ion solution. The precious metal ion solution is separated from the slurry and subjected to recovering techniques to recover the precious metals.

摘要： In the hydrometallurgical recovery of metal values from ores and the like in which a metal bearing source is reduced in the presence of at least one additive at temperatures ranging from about 500.degree. to about 900.degree. C. and thereafter extracted, the improvement of said process comprises pretreating a portion of process tails from a preceding run with the additive prior to the reducing roast. The additive which is used to pretreat the minor portion of the feed stock may comprise that which is recovered from the roaster offgas and admixed with a portion of the tail stream from the extraction step.

摘要： Copper is recovered from native sources, and scrap sources, by accelerated solution thereof into ammonia plus ammonium carbonate solution with a catalyst which oxidizes copper from copper metal to the cuprous and from the cuprous to the cupric state, the catalyst being chelated iron, which is returned to its effective ferric catalytic state, and maintained in solution as a chelate by the oxidation of the medium in which the solution takes place. Following solution of the copper, recovery can occur in virtually any conventional manner.

摘要： A basic copper salt selected from basic copper carbonate, basic copper sulfate, basic copper acetate, basic copper citrate, and basic copper nitrate is manufactured by contacting copper metal with an aqueous solution having ammonia; an acid selected from carbonic acid, sulfuric acid, acetic acid, nitric acid, or citric acid; and oxygen, under conditions where the copper metal is converted to the basic copper salt; and then recovering the basic copper salt. The most economical embodiment is where the ammonia is present in the aqueous solution is in an amount between about 6.7 g/l and about 15 g/l calculated as NH3, and the pH of the composition is between 8 and 10, and the temperature of the composition is between 25° C. and 100° C. The method is particularly useful if the basic copper salt is basic copper carbonate. The basic copper carbonate produced has the formula: (CuCO3)x(Cu(OH2)y, where y is 1 and x is between 0.1 to less than 1; or where y is 1 and x is 1, or where y is 1 and x is between 0.5 to less than about 0.95, or where y is 1 and x greater than 1.

摘要： This invention provides a two-stage leaching procedure for manganese nodules for obtaining directly from a second leaching stage a substantially pure stream of copper free of other metal values, the other metal values, including manganese, nickel and cobalt, having been previously extracted in an earlier leaching stage. Both leaching operations are carried out utilizing an ammoniacal aqueous solution on a reduced manganese nodule.
