Sulfide Ores. Sulphide ores were mostly created by i the intrusion of molten magma from the mantle into the crust of the earth and ii the formation of localized metalrich sulphide ore bodies by sequential solidification andor hydrothermal leaching and precipitation.

In a large number of the older operating plants that use conventional rod millball mill grinding, there is a tendency to convert the conventional grinding circuits into a SAG millball mill grinding configuration. In the flotation of copperzinc massive sulfide ores, the flotation properties of copper and zinc are determined by the
sulphide ores, the intergrown nature of the constituent mineral usually result in a poor liberation of the associated minerals. As a means for improving the efficiency of conventional grinding circuits, the liberation of minerals and to reduce costs associated with size reduction, several approaches could be adopted.

This invention relates to an integrated process for recovering value metals from sulphide ore which includes the steps of bulk sorting 16 and screening 2428 crushed ore. The sortedscreened coarse ore stream is ground and classified 20 to provide a coarse fraction 34 suitable for coarse flotation and a first fine fraction 38 suitable for flotation.
Sulfide British English also sulphide is an inorganic anion of sulfur with the chemical formula S 2 or a compound containing one or more S 2 ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide. Hydrogen sulfide H 2 S and bisulfide SH are the conjugate
The ore is milled using conventional grinding and flotation. Reverberatory furnaces and PierceSmith converters are used to smelt the concentrate, and electrolytic refining is used. Byproducts of the mine are molybdenite from the flotation circuit, gold and silver from electrolytic slimes, and sulfuric acid from smelter offgases.
Monong Huang University of British Columbia 5176350 Stores Road, Vancouver, Canada V6T 1Z4 ABSTRACT High pressure grinding rolls HPGR machine has been increasingly popular in mining industry due to its high energy efficiency in comminution process and its potential benefits to downstream operations, which are mainly caused by microcracks produced during the comminution process.

Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. FeO s SiO2s2 slag This is very similar to the removal of impurities in the blast furnace. The liquid left is a

Growth in HPGR applications in diamond iron ore, copper and gold ore processing. Source Knecht 2004 Baum 1997 and Baum et al. 1996, 1997 showed on the basis of photomicrograph and
Influence of grinding method on complex sulphide ore flotation a The present work deals with pilot plant investigations on the influence of conventional and autogenous grinding methods in the flotation of a complex sulphide.
The ore was milled to target grinds of 55 , 60 , 65 , 70 and 75 passing 75 m respectively, at a grinding pressure of 600 kPa, air temperature of 300 K. For the benchmarking grind of 65 passing 75 m, the ore was also milled using heated air of temperature of 373 K and at elevated grinding pressures of 800 kPa and 1000 kPa.
Sulfide Ore Grinding Flotation. Apr 24 2019160183 the ground ore of a coarse size indicates that may have many associated fluorite ore lumps these lumps may increase the silica content decrease the flotation effect if the grinding particle size is too fine although quartz and fluorite have been dissociated from the monomer it will cause the fluorite losing easily thus reduce the recovery rate

For Goldbearing sulfide ore, it occurs in both the chemically bonded state and as nachosized grains of metallic gold. In roasting or pressure oxidation, the sulfide matrix would be destroyed so that gold could be converted to the metallic form,

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 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
