The kinetics of zinc silicate leaching in sodium hydroxide

2019-2-28 · zinc silicate and zinc sulphide leaching (Souza, 2007). Both routes use acid leaching to dissolve zinc from the ores/concentrates and special care is taken to avoid the formation of silica gel. This can be achieved by a stepwise addition of sulphuric acid, whereby the silicate is dissolved with a minimum silica gel formation (Souza et al., 2009).

Various mineral processing operations to produce pure metals from mineral ores generate sludges, residues, and other unwanted by-products/wastes. As a general practice, these wastes are either stored in a reservoir or disposed in the surrounding of mining/smelting areas, which might cause adverse environmental impacts. Therefore, it is important to understand the various characteristics like ...

Zinc - Essential Chemical Industry

2020-2-20 · However, any iron sulfide present in the ore will be converted to iron(III) oxide, which reacts with zinc oxide to form zinc ferrite: In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter.
