Jan 24, 2017 Relationship Between Prices Under Corporate Income Tax and for Royalties . Royalty rates: copper 3.5% of copper value; gold 5% of gold value. CIT rate: . Is the mine's beneficiation equipment used to process ores.
Magnetite has minimal value as raw ore requires massive beneficiation before it is saleable to the steel industry;. Similar beneficiation process to copper, gold
Flotation is considered to be the most cost effective method for concentrating also for beneficiation and separation of difficult to treat (refractory) gold ores.
Beneficiation and value addition of minerals before export is one of the four key with 60 different economically exploitable mineral resources including gold,
