Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.

A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide leaching without the costly oxidation stage to release the gold from the sulphides. And on-site dor production avoids the off-site costs of transport and smelter charges, but usually with lower recovery (flotation recovery then oxidation-leach recovery) so

WO2014155753A1

Provided is a method for pretreatment of gold ore in order to leach out gold from gold ore containing pyrite, with which it is possible to suppress the generation of sulfide dioxide and to improve the leaching rate of gold. A method for pretreatment in order to recover gold contained in gold ore containing pyrite (FeS 2 ) by wet treatment, the method containing a step in which pyrite in gold

The first commercial Hot Leaching technology was constructed in 2009 at the Crocodile Gold Corp's Fosterville BIOX operation near Bendigo, Australia. Suzdal produced 75.3 koz of gold in 2015. The HiTeCC circuit will produce an additional 9 -14 koz of gold dor per year for 10 years, a total of approximately 90 - 140 koz, generating

A heated leach process at the Fosterville Gold Mine in Victoria has been described with increased gold recovery from this preg-robbing ore (Binks and Wemyss, 2011). 6. PRACTICAL ORE CHARACTERIZATION Newmont and other gold-mining companies have used a preg-robbing analytical method to quantify the preg-robbing characteristics of refractory gold

Heap leaching, shown in Exhibit 3, is the least expensive process and therefore, low value ores are most often treated by heap leaching. In 1993, heap leaching account ed for 39 percent of gold production.9 In many cases, heaps are constructed on lined pads with ore sent directly from the mine with little or no preparation. However, at about

These deposits form in the shallow crust, 0.5 to 1.5 miles at temperatures of greater than 300C in subaerial volcanic settings. Steeply-dipping, open-space veins are common. Quartz is the principal gangue mineral and can be accompanied by chalcedony, adularia, illite, pyrite, calcite, and rhodochrosite.

The object of calcining or roasting certain ores before treatment is to dissipate the sulphur or sulphides of arsenic, antimony, lead, etc., which are inimical to treatment, whether by ordinary mercuric amalgamation or lixiviation. The effect of the roasting is first to sublimate and drive off as fumes the sulphur and a proportion of the objectionable metals.

Initial leach temperatures of 40 degrees Celsius were adopted with the view to use waste heat from the bacterial oxidation circuit which operates at a similar temper ature.

Occasionally, carbon columns will be used with tank leaching operations, also, especially if the mine has a dual leach system, heap leach of low grade and tank leach of high grade. Carbon columns consist of large columns (5 to 8 ft diameter) and 15 to 20 feet in height, charged with activated carbon.
