Activated flotation circuit for processing combined oxide and sulfide ores . united states patent application 20140197076 . kind code: a1 . abstract: a method of extracting targeted metallic minerals from ores that contain sulfide metallic minerals along with oxide minerals, carbonate minerals, silicate minerals, halide minerals or combinations.
Chromite was leached with com. h2so4 using a ball mill autoclave. this process yields cr2(so4)3 for use in the chem. industry or to produce cr-metal. an empirical formula was obtained to det. the dependence of the rate of cr dissoln. on temp., grain size of chromite, h2so4.

May 01, 2019 before leaching with alkaline na 2 s and/or cyanide solutions, the concentrate or calcine was wet-milled in a ball mill to be over 80 wt% -45 μm. the alkaline na 2 s leaching conditions were liquid-solid mass ratio 3:1, temperature 80 c, stirring speed 300 rpm, na 2 s 0–15 g/l, naoh 20 g/l and leaching time 1.

Sep 26, 2019 oxide ore processing and sx/ew . after crushing oxide-type copper ores, such as azurite (2cuco 3 cu(oh)3), brochantite (cuso 4), chrysocolla (cusio 3 2h 2 o) and cuprite (cu2o), dilute sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. as the acid trickles through the ore, it combines with the.
Stage 3: roasting at this stage of the process, the chemical reactions begin. they convert the copper minerals into copper metal. we can illustrate the types of process using the example of chalcopyrite – cufes the formula, it is clear that iron and sulfur have to be removed in order to produce.
Teck and vale operate their medium temperature copper and nickel sulfide concentrate leaching processes at 150 c. “medium temperature” is used to describe a variety of processes that operate above the melting point of sulfur (119 c) but below the temperature where sulfur become highly viscous (159 c). during leaching, and depending upon various process parameters, iron (fe) may.
Todorovsky et al. creases the conversion efficiency decreases, whereas extraction (1997) studied the effect of mechanoactivation on re leaching experiments showed that eu and y extractions improve when sol- recovery by centrifugal ball mill in air and suspension with the vent organic ratio increases until to obtain y and eu extraction same acid.
