The invention further relates to a process for treating the sulfide ore through calcination at temperatures in the range of 500° to 900° C. with the addition of a gas containing free oxygen to produce a metal oxide containing solids mixture and an SO 2-containing gas.
2021-5-3 Sulfide gold ore is a rock gold ore in which natural gold and sulfide (usual pyrite) coexist. The symbiosis of natural gold and sulfide means that pyrite is a gold-carrying body.
1997-2-24 The ore which contains gold and at least one of the metals silver, copper, nickel, zinc or iron is calcined at temperatures in the range from 500° to 900° C. with the addition of oxygen-containing gas, thereby producing a metal-oxide-containing solids mixture and a SO 2-containing exhaust gas.The SO 2 containing exhaust gas is brought in contact with aqueous solution, thereby producing a

A. Charitos, in Gold Ore Processing (Second Edition), 2016. Abstract. Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high
2021-10-28 Properties of gold sulfide ore Gold sulfide ore is the inorganic compound with the formula Au2S. It is the principal sulfide of gold and decomposes to gold metal and elemental sulfur, illustrating the "nobility" of gold. In nature, the covalent radii of gold sulfide and silver are similar, and the two will form a solid solution. Brief

2016-1-1 The ore contains on average 1.1% sulfide sulfur, 1.1% organic carbon and 2.9% carbonate carbon. The relatively high carbon content affects the gold recovery through preg-robbing during leaching. After roasting in the CFB, the carbon content is reduced to such low levels that the gold recovery increases by approximately 20%.
2020-3-17 High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly
2021-11-1 Sulphide ores are transformed into oxides by the process of roasting. In this process, concentrated ore is heated in the presence of surplus air. Example: Zinc blende, ZnS, a sulphide ore of zinc, is roasted in the presence of air. Onroasting,zinc sulphide gets transformed into zinc oxide.

2014-12-1 The data in Table 2 indicates that the gold in the ore primarily exists in the form of native gold with a distribution rate of 95.72%; the secondary forms of gold exist in sulphide and iron mineral with distribution rates of only 1.90% and 0.76%, respectively.

These gossans were used by prospectors as guides to buried ore. In addition the oxidation of those sulfide deposits which contained gold, often resulted in the concentration of gold in the iron oxide and quartz of the gossans. Goldbearing limonite gossans were productively mined in the Shasta County, California mining district.
2012-2-3 Limonite is a common ore of iron and is always secondary in its origin, formed through the alteration or solution of previously existing iron minerals. Pyrite is often found altered to limonite, the crystal form being at times preserved, giving limonite pseudomorphs.
