hydrometallurgy sx phase separation tests

I was doing somephase separation testsin the lab today and we saw thatseparationis faster when adding organic to the aqueous at a slower rate (while stirring the aqueous). Any way i can relate this back to the plant? Our A: O ration is 1.2:1, but both feed into the mixer impeller so the essentia

Copper OreHydrometallurgyand Pressure Leaching Copper

Copperhydrometallurgyis a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copperhydrometallurgyprocess typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

Jun 01, 2012· Afterphase separation, both phases are analyzed for metal concentration The McCabe–Thiele plot illustrated the possibility of > 99% of copper stripping at 2 counter-current stages at A: O ratio of 1:4. To confirm the above prediction, a 2-stages counter-current simulation (CCS) study was performed (up to 6 cycles) at the above mentioned ...

The precipitation of jarosite group phases is used inhydrometallurgy, especially the zinc industry, to control Fe, sulphate, alkalis and other impurities (Groat et al., 2003; Murphy et al., 2009). Hydrometallurgical treatment of Zn sulphide ore involvesseparationof Zn from Fe, as most Zn processing concentrates contain 5%–12% Fe.

Thetestcan last 72 hours.At the end of thetest(72 hours), after the solid-liquidseparation, the cake is washed. The pregnant solution and the cake are assayed for Ag, Pb, and Zn. The final pH and free acid are analyzed in the final pregnant solution. The slurry is checked at 2, 4, 8, 24, 48 and 72 h for pH.

Solvent extraction (SX), sometimes called liquid ion exchange, is used to selectively concentrate and purify a desired element after it has been dissolved in an aqueous solution. The liquor is contacted with an organic solvent, chosen for its selectivity towards the element or elements of interest.
