These consist of zinc and iron sulfide depressants which are added to the grind and a collector and frother for the lead-copper sulfides. The zinc is floated with additional quantities of a collector and frother after conditioning with lime and copper sulfate. The pH of the lead circuit is approximately 8.0 and the zinc is 10.5 to 11.0.

decreased while silica, sulphur, iron and lead contents increased. Dissolution results showed that the leaching rate of copper was lower than that of zinc. The highest recoveries of zinc and copper were obtained at a leaching time of 180 minutes, stirring speed of 160 rpm, particle size of 75 µm and a concentration of 1M H2SO4/1M H2O2. It was observed that the leaching rate of zinc and copper ...

In rare circumstances, mineralogy and metallurgical response considerations necessitate an initial bulk lead-zinc concentrate with the lead and zinc minerals subsequently separated in a selective flotation step. Under this scheme, a bulk galena and sphalerite flotation concentrate is produced at pH 6.5 (modified with H2SO4) with some copper sulphate addition to ensure full sphalerite ...

for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some ores of copper. Gold ores may yield only gold, but silver is a common associate. Nickel ores are always associated with cobalt, while lead and zinc always occur together in ores. All other ores are complex yielding a number of metals.
