Apr 20, 2018· Many experimental investigations have been carried out on silver recovery from silverbearing wastes through chloride leaching (Yazici and Deveci, 2015, Zhang et al., 2012). However, the recovery of silver from lowgrade tailings, especially from magnetic tailings, is rarely reported.

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process. First the lead ore is ground into small particles that are less than, giving the ore a texture similar to table salt.

Aug 13, 2008· Smelt the lead/silver ore. Continue to heat with zinc (at about 10 of lead to 1 of scrap zinc). Skim off the zinc (if you let the whole lot cool together, you may be able to liberate the zinc using a hammer the point ofd contact can be quite fragile. Now heat the zinc in an oxygenrich flame on a bed of bone ash.

The associated silver is mostly concentrated to the lead concentrate. With the process utilized in this work, a lead concentrate of % Pb with a recovery of % and a zinc concentrate of % Zn with a recovery of % are produced. The silver recovery in the lead concentrate is %.

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of .

application of wholeoreleaching may be limited and that the concentration of zinc, or at least the separation from acidconsuming gangue minerals, prior to leaching is essential to the successful recovery of zinc from these deposits. The recovery of zinc is dependent on an understanding of the geology of the deposit, the

The study aims to recovery of silver minerals from zinc leach residue by flotation method with mixed collectors, namely, ammonium dibutyl dithiophosphate (ADD) and diethyl dithiocarbamate (DD). The effect of key parameters,, grinding fineness, dosage of collectors and dosage of sodium chloride on the flotation performance was investigated.
