1998-7-15 · 3) To make the "wrought" you start with high grade iron ore (you may have to dig it up your self). It then needs to be roasted and crushed into sand or pea gravel size grains. 4) Ore needs flux. Some ores are self fluxing others are not. You need the chemistry of the ore OR need to run a dozen of so experimental smelts to figure it out.

Hydrometallurgy of precious metals recovery

1992-6-1 · The hydrometallurgical process for the treatment of gold and silver ores remained unchanged for the first 70 years of this century, and consisted essentially of leaching in cyanide solution followed by solid-liquid separation, with the solid residues being washed as efficiently as possible, and the leach liquor being treated by zinc cementation to recover the precious metals.

The cyanide heap leaching behavior of cupriferous gold ores

To develop a fundamental understanding of cyanide heap leaching of low-grade gold ores, with significant copper mineralization, two sets of column leach tests were operated under two different leaching solutions. In one set, four 1.5 m tall column tests were leached with sodium cyanide solution. In the second set, another four columns were leached with solutions of cyanocuprate …

The recovery ratio of REO is 28.87% to the original ores and 32.24% to the ore tailings. The beneficiation work of Baotou Damao Rare Earth Co., Ltd and Boyu company of Baiyunebo iron mine concerns ores which have a great amount of magnetite using the weak magnetic separation-flotation technique. The original ores are ground to 90% -0.074 mm.

Modeling the cyanide heap leaching of cupriferous gold ores

A mathematical model of cyanidation heap leaching of cupriferous gold ores which includes the speciation of all cyanide, cyanate, thiocyanate, hydroxide and sulfate complexes, and their corresponding copper and gold precipitates, was developed to facilitate the treatment of these complex ores. The concepts of back mixing and solution retention are represented by two …
