Flotation concentrate cyanidation residues were subjected to open circuit flotation to produce separate lead and zinc concentrates. Cleaner flotation yielded lead concentrates that assayed 3,324 g
The established lead zinc ore flotation processing scheme is to add zinc sulphate ZnSO4 to the grind to control metal ion activation sphalerite depression. Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead zinc flotation section. Which flotation scheme used in the differential copper lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate.
01/01/2010· In this research work, selective depression of pyrite in the flotation of a low grade leadzinc ore containing 31 pyrite was investigated in the absence and presence of Acidithiobacillus ferrooxidans. Pyrite was significantly depressed with these bacteria using the optimum dosage of reagents.
Lead was recovered after conditioning, utilizing cyanide as the base depression scheme to control sphalerite and pyrite. In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal. The flowsheet schematic and summary of test results.
It is reported that more than 90 of non ferrous metal ores copper, lead, zinc, etc. adopt flotation process, especially for those with fine grainplex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low grade ore then enrich multiple high grade concentrates.
Where the oxide lead minerals are present in appreciable amounts, it is the usual practice to float the lead sulfides first. Then, if present, the zinc sulfide is floated, followed by flotation of the lead minerals. Either sodium sulfide or sodium hydrosulfide is used as a sulfidizing agent.
At Rosh Pinah lead zinc concentrator in southern Namibia the major valuable minerals being chalcopyrite, galena and sphalerite, sequential Cu Pb Zn flotation is used.
