Some prospectors are interested in the methods of processing sulfide ores to extract their values. The two of the best known processes are smelting and roasting. The two are actually different methods, but both involve heating the ore to high temperatures. Technically, any methods which consist of processing ore by heating it are called pyrometallurgy.

During the cyanidation process of ore, the surface of gold particles is in contact with the cyanide ore slurry, and the surface of gold particles may form sulfide film, peroxide film (such as calcium peroxide film), oxide film, insoluble cyanide film, etc. Surface passivation significantly reduces the oxidation and leaching speed of the gold particle surface.
Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain specifically, roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, by froth flotation.

High sulfide gold ore refers to 20% 30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotationcyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for
Flotation process are widely used for improving the sulfide type gold ore grade. The ore pulp slurry is pumped to flotation cells for extracting.

Flotation is a method that is widely used in gold ore processing plant to process the rock gold,commonly used in dealing with highly floatable sulfide minerals containing gold ore. Flotation process can maximum enrich gold to the sulfide mineral, tailings can be abandoned directly, the cost of processing plant is low, 80% of China''s rock gold are used in this method.
There are mainly several methods of gold tailings reprocessing: 1. The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation and their combined processing technology.

Jun 02, 2020#0183;#32;In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a costeffective approach
For example, ore that has a high level of sulfide minerals or carbon (or both) is called refractory ore. Refractory ore resists normal processing methods as the high sulfide minerals trap gold particles, making it difficult for the cyanide to reach the gold and leach it. Heating. To leach gold from refractory ore, it must be subjected to high temperature, high pressure and/or oxygen. Newmont treats refractory ore in two
May 27, 2016#0183;#32;In fact, we have tons of sands coming from the gold extraction process using cyanide. These sands still have in average 20gr/ton of gold. The problem is that we haven''t found a reliable process or technology to effiently recover the gold (at least 70% of the remaining gold) because these sands contain elements making cyanidebased treatment
method for processing the refractory sulfide ore is the method of hydrochlorination along with thiocarbamide. As a method of processing the goldcontaining tailings of the refractory sulfide concentrates we chose the method of electrochemical oxidation of sulfides in the ore pulp with the use of various chlo

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an allcyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
with gold molecules. With many sulfide ores, the ore cannot practically be ground down fine enough to expose the gold particles. The objective of pretreatment for these ores is to remove enough of the sulfide so that at least a small portion of all gold particles are directly exposed to the elements. Processes available for treatment all involve oxidation of sulfur to form water soluble sulfates or sulfur dioxide.
