Sulphide Mineral Indicators For Gold – BC Gold Adventures

The main sulfide mineral associated with tin and the biggest matrix for tin ore. It is typically found in igneous and metamorphic rock formations. The old timers knew the significance of sphalerite as a potential gold indicator and called it “blackjack” or “rosin jack.”. Sphalerite comes in a range of colors, including grey or greyish

Apr 18, 2016 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 all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Oct 20, 2017 A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydro-metallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electro-deposition of the cobalt and zinc from the strip

The most common sulfide crystalling in this manner is galena (PbS), the ore mineral of lead. A type of packing that involves two sulfide ions in each of the octahedral positions in the sodium chloride structure is the pyrite structure. This is a high-symmetry structure characteristic of the iron sulfide

inorganic chemistry - Why are the sulfide ores generally

Jun 27, 2018 The concentrated ore must be converted into a form which is suitable for reduction. Usually the sulphide ore is converted to oxide before reduction. Oxides are easier to reduce. Thus isolation of metals from concentrated ore involves two major steps viz., (a) conversion to oxide, and (b) reduction of the oxide to metal

Metallurgy and Various Types of Ores use in Metallurgy

A sulphide ore is converted into a metal-oxide by heating the ore in air. 3. Reduction of metal-oxide : Metal oxides are reduced by processes such as electrolytic reduction. Metal is obtained, but this may not be pure metal as there may be mixtures of metals. 4. Refining of impure metal : In a given ore, there may be more than one metal. To

Process and apparatus for the electrowinning of metals from sulphide ores wherein a sulphide ore is initially leached in a water soluble sulphide solution, alkali is then added, and the resulting solution is electrolyzed so as to deposit metal at the cathode and obtain water soluble sulphide as a by-product. The process is particularly suitable for obtaining antimony from stibnite

Sulfide Ore - an overview | ScienceDirect Topics

Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte. A key element in the recovery of the metals is the solidification of the matte which separates into a sulphur
