Guides For High-sulfide Gold Processing

High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

sulfide vs oxide ore - levneekologickedrevostavbynaklic

differences in processing sulfide and oxide gold ores. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m

A fresh approach to sulfide ores - CIM

Jun 26, 2017  T he copper mining industry is reaching a turning point. Surface oxide deposits are depleting and copper miners are turning their attention to untapped sulfide ores found deeper underground. However, sulfides require more expensive processing techniques since they are not responsive to standard technologies that are used in oxide heap leaching.

Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Sulfide Ore - an overview ScienceDirect Topics

A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.

Fungal pretreatment of sulfides in refractory gold ores ...

Changes in sulfide sulfur concentration and the formation of oxide phases during fungal treatment were confirmed using Raman spectroscopy and X-ray diffraction analysis. These results suggest that P. chrysosporium is a potential microorganism for oxidative decomposition of metal sulfides associated with refractory gold ores.
