Clover Alloys Processing Plants

Processing at Rietfontein Plant

The Rietfontein operation is located in the western area of the Bushveld Complex close to Rustenburg. The facility boasts an impressive three stage crushing plant that allows it to treat any form of Run of Mine (ROM) feedstock. The washing facility concentrates on the production of specialist high grade products such as foundry and chemical grade concentrates. The chrome sand concentrates are sold both in the local South African market and is also exported to various international markets including China, USA, Europe, Japan, Korea and Brazil..

Processing at Benoni Plant

The Benoni plant operates in the same fashion as the Rustenburg operation but on a smaller scale. Feedstock is however also sourced from local foundries within the larger Johannesburg area. The plant mainly produces metallurgical grade concentrates ranging from 42% to 46%.

Rustenburg Chrome Mine

The Rustenburg Chrome mine is renowned for it's quality orebody, which hosts both the Lower Group (LG) and Middle Group (MG) reef horizons. The mine employs underground and open cast mining and also treat historical tailings. The mine produces chrome concentrate and Platinum Group Metals (PGM's) from their ore through a crushing, milling and washing process. The main chrome concentrates produced includes Foundry sands, Chemical and Metallurgical grades which are exported to international markets.
