Oct 02, 2017 The PGM ore is initially treated in primary and secondary crushers after which it is sent to rod and ball milling circuits. The milled PGM ore is treated using gravity separators and flotation cells xanthate and dithiophosphate collectors are typical reagents used for flotation at a pH of 7.59 .Online Chat
On the surface the ore is crushed and milled into fine particles. Wet chemical treatment known as froth flotation produces a concentrate which is dried and smelted in an electric furnace at temperatures over 1,500 C. A matte containing the valuable metals is transferred to converters to remove iron and sulphur. PGMs are then separated from the baseOnline Chat

Generally, 90-97 grade of graphite concentrate can be obtained after the graphite flotation process. For the different graphite ore properties, the graphite mining processes are also different. Application Graphite mining processes are mainly applied in the various graphite ore with different types of crystalline and graphite ore accompanied with silicate minerals, such as mica and pyrite.Online Chat
China has established a graphite refining and fine powder processing production line in Nanxu, Beishu, Liumao, Xinghe and other graphite processing plants. The purification method is mainly chemical purification. Graphite chemical purification of the most mature process is the use of caustic and graphite melting at 700 , after washing to neutral, plus hydrochloric acid treatment, washing, so thatOnline Chat

Jan 01, 2005 Alloys containing gold, silver, PGMs and other metals are usually first processed using the Miller process to remove base metals and cast into anodes. GoldPGM alloys are processed using the Wohlwill electrolytic refining process, also known as the gold cell. The Wohlwill cell uses impure gold alloy as anodes and deposits pure gold at the cathode.Online Chat
