Xinhai washing thickeners include two layers washing thickener and three layers washing thickener. Taking the three layers washing thickener as an example, the pulp is fed by a feeding tube, and the pulp that settles freely in the rake area is further concentrated by the pressure of the scraper blade, gradually scraped towards the center of the pond, then enters the next layer pond through the ...
Overflow from the washing thickener passes to the low grade precipitation section and is treated similarly to the high grade solution. Barren solution is circulated back to both cyanide sections. Until 1956, a second 500 ton per day mill operated using a pre cyanidation flowsheet.
Washing Thickener arra .au. The continuous ore discharge method can reduce the multiple cycle of liquid gold, while extending the time of pulp staying in the washing thickener to improve the leaching rateCountercurrent washing, large capacity and high washing efficiencySmall area taken, reasonable structure and low cost of operation and maintenance.
as reduces the amount of leaching reagents required. Many gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as de watering systems that use cyclones only or cyclones and high rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant
Hello there, am interning at a gold mine where there are problems with the clarity of the overflow of the pre leach thickeners. Initially, only flocc was used at 0.1% strength. Now we are testing a coagulant as well at different dilutions on the plant. The clarity has improved over the 2 weeks w
Increasing wash water to 3.5 tons of water per ton of solids, or a wash ratio of 1:1.1, raises recovery to about 95% . Adding one stage and keeping wash at 2.5 tons of water per ton of solids, provides a recovery of 96.2% .
