Nonferrous mining typically refers to critical and strategic metals, which include copper, nickel, cobalt, and precious metals, including platinum, palladium, gold and silver. A sulfide is any compound or mineral in which a metallic ion is bonded with sulphur ions. Sulfide deposits can contain copper, nickel and precious metals.

Slättberg is a historic mining camp hosting cobaltnickelcopper rich massive sulfide mineralization that occurs within a two kilometer belt of historic nickelcopper mines. The Project contains drill defined massive sulphide mineralization that extends to ~100 meters in depth, and remains open for expansion at depth and along strike.

The cobalt minerals are then floated by using sulphuric acid to decrease the pulp pH to 4. Sodium sulphide is conditioned in the pulp. Cobalt is floated using a combination of xanthate and dithiophosphate and/or MBT. Depending on the cobalt mineralization, use of an activator such as copper sulphate

Solvay offers a variety of unique solutions for nickel and cobalt processing. Flotation. Flotation reagents from our AERO®, AEROFLOAT® and OREPREP® brands enable the recovery of sulfide nickel/cobalt minerals from ore. AERO polymeric depressants, such as AERO 7261A, help in making a clean separation by depressing nonvalue sulfide minerals.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24

Recovery from nickelcobalt sulfide concentrates (Sherritt process) The Sherritt process is a hydrometallurgical process named for Sherritt Gordon Mines Ltd. (now Sherritt International) of Sherridon and Lynn Lake Manitoba Canada, based on the older Forward process developed by Dr. Frank Forward for the recovery of copper and nickel from those same mines.

Geologically, it belongs to the magmatic segregation model for mineral deposits. Sulfur rich ultramafic plutons produce immiscible sulphide phase droplets in a silicate liquid from which various nickel, copper and cobalt crystalize as the settle to the base of the magma chamber. Las Aguilas plutons intrude very old gneissic basement rock.
