The Macraes process plant flowsheet is relatively complex with several parallel feed streams treated through various integrated flowsheets. The flowsheet is represented schematically in Figure 1. The main energy consumers are in the sulfide ore processing stream. The single stage SAG mill
OUTOTEC HITECC PROCESS
The process design incorporates energy-efficient heat exchangers and the byproducts of the process are benign and can be safely deposited into a tailings storage facility. Robust technology The operation of both the Fosterville and Suzdal HiTeCC plants have confirmed the robustness and simplicity of the HiTeCC process. The process is not sensitive
Process for recovering precious metals from sulfide ores - Justia
23. A process for extracting precious metals from sulfide ore comprising: contacting an ore which contains elemental and sulfidic metals selected from the group of: platinum group metals gold silver iron or copper with salt which contains greater than 60% potassium chloride in the substantial absence of added promoter metal chlorides to produce an ore/salt mixture having a salt to ...
How industrial plants benefit from apron feeder magnetic ...
the ore is normally sized 15.2- to 20.3-cm (6- to 8-in.) the main purpose of the suspended elec-tromagnet is to protect the belts and to avoid the clogging of the chutes. Tramp iron measuring less than 10 cm (4 in.) is not typically harmful to the belts or chutes so electromagnets are set to cap-ture only the larger pieces of tramp iron.

Questions About Gold Flotation Processing Technology - Xinhai
Gold flotation method is the main processing method for gold-bearing sulfide ores. The main characteristics of this kind of ores are often gold silver lead sulfur and other minerals. Metal minerals include pyrite sphalerite galena chalcopyrite etc. Gangue minerals are mainly quartz and include calcite barite and other minerals.
Summary of Gold Extraction Process - cnfreereagent.com
The chute of the cone concentrator is fan-shaped the chute length is about 1 m the feed end is 125-400 mm wide and the chute surface is inclined. The ore slurry is fed from the center of the upper end and distributed through the distribute cone to enter the extraction cone.
Sulfide Ore - an overview | ScienceDirect Topics
Sulphide ores are a major source of Cu Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S which forms a gas and (2) Fe which forms predominantly FeO and then partitions to a slag phase which covers the matte. A key element in the recovery of the metals is the solidification of the matte which separates into a sulphur-rich matte and metal-rich liquid.
Sulfide Ores - an overview | ScienceDirect Topics
Nickel sulfide ores are processed by heap leaching in Sotkama eastern Finland (Talvivaara 2011). The process entails the following: (a) open-pit mining of 0.2% Ni 0.5% Zn 0.1% Cu and 0.02% Co sulfide ore; (b) four-stage crushing; (c) rotary kiln agglomeration with sulfuric acid; (d) stacking the agglomerate in 8 m high heaps; (e)

ores and in the ore body mined by Molycorp. According to Molycorp personnel the differences in levels of barium lead copper and zinc in the Pond Uranium Material and Drummed Uranium Material was to be expected for two reasons. First the material accumulated in the ponds was generated from ores managed up to 1985.
