Pyrite forms in some of the most interesting natural structures, including nearly perfect cubes and octahedrons. Another interesting formation is what is known as penetration twinning, where two or more crystals are intergrown. Pyrite deposits can contain small amounts of other minerals or gems such as cobalt, nickel, silver and true gold.
Process Flow Sheet. Copper Circuit: Resin in pulp (RIP) allows Cu leaching in acidic environment. PH Pyrite Circuit: Standard concentrate flotation after neutralisation and polishing grind to p80 75um. PH Gold Circuit: Gold extraction from both pyrite leach and tail by standard carbon in leach (CIL).

Coal sales totaled Mt in 2Q19, % lower than production in the same period, as a result of an increase of sales with DAP and DAT INCOTERMs7. The performance in 1H19 and the current challenges at the processing plants led Vale to revise its 2019 production guidance to about 10 Mt in 2019.
pressure oxidation solids with acidic raffinate at atmospheric conditions depending on the pyrite content in the concentrate. Sulphur in the concentrate is primarily oxidized to elemental sulphur instead of sulphate. The presence of chloride in the autoclave helps to increase the rate of reaction and reduce sulphur oxidation.
