Apr 05, 2017· Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall.

Nov 28, 2021· We achieve a concentrated ore with a high percentage of metal by eliminating these impurities. The concentration of ore, also known as ore enrichment, is the process of removing gangue particles from ore in order to enhance the percentage of metal in the ore. The difference in physical or chemical properties of the ore and the impurities ...

Solubilities of the assemblages chalcopyrite (CuFeS 2) + pyrite (FeS 2) + bornite (Cu 5 FeS 4) and copper + chalcocite (Cu 2 S) have been measured in subcritical aqueous solutions of NaCl and NaHS + H 2 S under the following conditions: 200 degrees to 350 degrees C; a range of pH within 2.5 of neutral in sulfide solutions, and 1.5 of neutral in chloride …

Solubilities calculated using the above data compare well with those observed in these experiments.If it is assumed that a solubility of at least 10 ppm Cu is necessary for significant ore transport, bisulfide complexes are potential ore carriers at 200 degrees C and a total sulfur concentration of 0.25 molal, or greater, at neutral to weakly ...

To evaluate possible bisulfide complexing in ore solutions, galena solubility was measured to 300 degrees C in 0 to 2.85 m NaHS solutions at H 2 S pressures of 0.8 to 75 atm. A maximum solubility of 47 ppm PbS was found in 0.5 m NaHS solution at P (sub H 2 S) = 75 atm, 300 degrees C. Derived from these solubilities were stoichiometries and …

In general, the solubility between 25 and 200 degrees C in an isochemical, isochoric system increases 4-7 times in bisulfide solutions, and the increase in H 2 S solutions is about twice as great as in HS (super -) solutions.Transport of HgS or Hg to form mercury deposits, by bisulfide complexes or, in strongly alkaline solutions, by HgS 2 ...

A solid solution, a term popularly used for metals, is a homogenous mixture of two different kinds of atoms in solid state and have a single crystal structure. Many examples can be found in metallurgy, geology, and solid-state chemistry.The word "solution" is used to describe the intimate mixing of components at the atomic level and distinguishes these …

Therefore, the nine equilibrium constants provide confirmed resolution of sphalerite solubilities in ore solutions having chemistries quite different from those used in the solubility experiments. Sample calculations of sphalerite solubilities in Kuroko-type massive sulfide ore fluids are given which demonstrate the effectiveness of cooling in ...
