1999. 8. 1. · The Kwekwe Roasting Plant is currently the only plant in Zimbabwe capable of processing gold concentrates in which the gold is contained in auriferrous pyrite, arsenopyrite and pyrrhotite. The plant was established in 1937 to custom treat mainly flotation and table concentrates characterised by sulphide host minerals such as pyrite, arsenopyrite, pyrrhotite, stibnite and chalcopyrite.

2021. 1. 30. · Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

According to scientists, roasting is the only commercialised process in Zimbabwe for the pre-treatment of refractory gold feed stocks for the subsequent cyanidation leaching results in 75% gold

Case】 In March , Xinhai contracted to build Zimbabwe 700tpd gold processing plant in Africa. The raw ore of this mine is quartzite gold mine, which is most oxidized ore or original minerals with low sulfur content. Therefore the processing technology is combined gravity separation and all-slime cyanidation

The Zimbabwe 700t/d gold mineral processing plant was an EPC+M+O project. The raw ore had a gold grade of up to 6g/t. Xinhai worked to ensure environmental protection and workplace safety, optimize plant layout, and shorten construction duration.

Cyanidation tanks were assessed and found to be leaking fluids thus also leaking gold. A program have been envisioned on how to improve these gold cyanidation tanks so that full gold recovery may take place.
