Environmental Code of Practice for Metal Mines

Magnetic separation has been used in Canada to separate iron ore from waste minerals, to remove magnetite (iron oxide) and pyrrhotite (iron sulphide) from base metal ores prior to flotation, and to recover magnetite from copper concentrates. Like gravity separation, magnetic separation tends to require the use of smaller amounts of process reagents than some other .

Heavy metal contaminants in inorganic and organic fertilizers

Commercial phosphate (P) fertilizers contain small amounts of heavymetal contaminants which were minor constituents in phosphate rock (PR). Animal manures and sewage sludges (biosolids) are the main organic fertilizers and the latter also may contain heavymetal contaminants. Heavy metals in biosolids may be found in the inorganic form or may be .

Manure Separation

The manure separation process essentially creates two products. The first product consists of the larger manure fibers that are mechanically removed. Depending on the process used, these fibers can still contain a significant amount of moisture, ranging from a high of 90% to a low of 70% depending on the equipment used.
