Abstract Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3 ), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption increases. Pretreatment is usually an oxidation step.

A two-stage roasting process, similar to that used for arsenic sulfide ores, can also volatilize antimony oxides and prevent adverse reactions such as the production of metallic antimony, which can coat the surface of gold particles (Nagy et al., 1966) or the formation of silver glasses in high-silver ores (Matsukawa and Sakai, 1956).

ANTIMONY, MERCURY, AND SILVER AND GOLD By D. F. DAVIDSON ABSTRACT The presence of selenium in some epithermal ores of silver, gold, and mercury has long been known. Recent work indicates that epithermal silver and antimony deposits are commonly highly seleniferous, and that gold and mercury deposits are only rarely so.

Processing of Mercury-Stibium Gold Bearing Ore of Djijikrut Deposit 310 Typically, in industrial practice the xanthogenate is used as a collector to enrich antimony ores with pre-activation of antimonite by lead cations [3]. Cations of lead sorptioning on the mineral surface soil concentrate and prevent at metallurgical processing. In

This article covers a hydrometallurgical method for processing of a gold-antimony flotation concentrate in alkaline sulfide solutions. Thermodynamic analysis of the reaction stibnite with sulfide sodium and sodium hydroxide was performed. The chemical and phase compositions of the investigated material, mainly represented by compounds of antimony, silicon, calcium, sulfur and iron are studied.

Keywords: electrochemical processing, gold-containing antimony ores, gold extraction The method for gold extraction from the residues of vacuum-thermal treatment of the concentrate of gold-containing antimony ore of Zopkhito (deposit) has been established by eco-friendly electrochemical method. The effect of main technological parameters on the

The reason of the gold mineral refractory There are so many types of reasons that caused the difficulty of gold ore processing, including physical element, chemical element, and mineralogical element.

From the perspective of metallurgical processing, gold ores can be classified into free-milling and refractory ores. ... type ores 8 Antimony sulfide ores Gold occurs mainly as native gold, with minor to moderate amount of aurostibite, either liberated or locked in sulfides.

Put the slag into the beneficiation process; Get the last antimony and gold through another round of calcination of ore slag 5. Blue clay gold ore ... 1 A common practice in processing pyrite gold ore is to remove as much gold and sulfide as possible by gravity treatment and/or flotation.

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.

Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite and/or arsenopyrite, unavailable for recovery by conventional leaching. In Sherritt's gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold. Subsequent treatment by ...

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

Compared with metals, antimony is a poor conductor of electricity and heat. Antimony is the 63rd-most abundant element in Earth's crust. It is less abundant than tin, arsenic and the rare earths, but more so than bismuth, mercury and silver. Antimony tends to concentrate in sulfide ores along with copper, lead and silver.
