Geochemistry of Phanerozoic carbonaceous black shales, sandstones .

The trace element geochemistry of marine black shales has been successfully used to interpret sediment provenance and deep ocean conditions during sedimentation. More recently, it has been proposed that certain pyritic black shales may act as sources of gold and arsenic for orogenic gold deposits. Four aspects of the geochemistry of the Phanerozoic black shales .

Gold Ore Roasting Techniques

 · Straight pyritic ores, where the pyrite is present in small quantities, usually yield their gold to fine grinding and cyanidation alone. Silver ores containing the values as polybasite, stephanite, pyrargyrite (the antimony sulphide), and proustite (arsenic sulphide) usually require roasting. Tetrahedrite is often refractory even after roasting.

In this research, the dissolution of gold ore (with FeS2 and FeAsS as the main sulfides) from Tianli gold mine, Liaoning province, China was investigated. The experiments were conducted in 500mL conical flasks containing 200mL of three different media, .

extraction of gold fromiron pyrite

Rcovery of gold in pyritic ores Mine. Recovery of gold in sulfide ores has fallen into several egories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery, and the best I have heard of is around 50 recovery. Get a quote

Gold cyanidation

The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to contain pyritic gold could not be extracted from this compound with any of the then available chemical processes or technologies. In 1887, John Stewart MacArthur, working in collaboration with brothers Robert and William Forrest for the .
