Dissolution regularities of smithsonite in methane sulfonic acid

Russian Journal of Non-Ferrous Metals, 2015
Methane sulfonic acid (MSA) was proposed as a clean and efficient leaching agent to extract zinc from smithsonite. Experimental variables such as acid concentration, reaction temperature, particle size, and stirring speed were considered. Results indicated that zinc leaching fraction increased with increased MSA concentration, reaction temperature ...

Alkaline Hydrometallurgy of Low-Grade Smithsonite Ores

2017
Low-grade smithsonite ores are leached using alkaline leaching solution. The zinc and lead concentrates can be obtained from lean oxidized zinc ores by alkaline leaching followed by two-step sulfide precipitation of lead and zinc sulfides. It is found that over 85% of both Zn and Pb and less than 10% of Al can be leached from the ore when the leaching ...

Smithsonite from the Rhodesia Broken Hill mines

Mineralogical Magazine and Journal of the Mineralogical Society, 1926
During an examination of zinc ores I had occasion recently to employ methods for the identification of smithsonite, and was surprised to find how scanty and indefinite are the data of its physical properties as stated in text-books. Most of the smithsonite known occurs either compact or as very small crystals many of which are of a composite nature. In
