A Review of Flotation Separation of Mg Carbonates
a cardinal stage in obtaining an efficient separation in the direct flotation of Mg carbonate [7]. One of the essential challenges during flotation in the presence of Mg carbonate is the occurrence of slimes. The low hardness of carbonates leads to slime problems. Carbonate slimes can cover the surfaces
Environmentallyfriendly oxygenfree roasting/wet magnetic
Jan 25, 2016 · After wet magnetic separation, the recovery rate of Co and Li, and graphite is 95.72%, 98.93% and 91.05%. Therefore, the spent LIBs can be recycled and used to produce cobalt, lithium carbonate, and graphite using the proposed system. There is no chemical solution added in the process, which saves the cost of treating secondary pollution.

Magnetic Properties of Low Grade Manganese Carbonate Ore
Rapid reduction roasting of low grade manganese carbonate ore by coal and biomass fuels from Hunan, China was investigated. Magnetic separation behaviors and magnetic properties of raw manganese ore and roasted manganese ores were analyzed. After reduction by coal and biomass fuels, the manganese ores demonstrate a new MnFe oxide phase, showing obvious mixed magnetic

Roasting (metallurgy) Wikipedia
Sulfating roasting oxidizes certain sulfide ores to sulfates in a controlled supply of air to enable leaching of the sulfate for further processing. Magnetic roasting. Magnetic roasting involves controlled roasting of the ore to convert it into a magnetic form, thus enabling easy separation and
Method for purifiion of calcium carbonate Minerals
Nov 25, 1997 · A method for lowering the iron content of calcium carbonate is disclosed. The method involves addition of an iron chelating agent to an aqueous calcium carbonate slurry, reducing the pH of the aqueous calcium carbonate by employing carbon dioxide containing gas, while maintaining the aqueous calcium carbonate slurry at an elevated temperature.
