FLOTATION OF COPPER-NICKEL SULFIDE ORES - DAVID WESTON

The ore treated in Example I was a copper-nickel sulphide ore containing an estimated average 40 percent of talcose type minerals. The sample contained 0.52 percent nickel in the form of pentlandite and 0.25 percent copper in the form of chalcopyrite. The ore was ground in a laboratory rod mill at 60 percent solids to a fineness of about 95 ...

The Mineral Gallery - Sulfides Class

The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...
