Copper activation option for a pentlandite–pyrrhotite–chalcopyrite .

In this scenario, response of the ore to copper activation may not be easily predicted. To explore the possibilities, flotation with various dosages of copper addition was investigated for this ore with specific interest in how the nickel recovery responds. The responses of copper, iron, cobalt and quartz were also monitored.

nickel and copper flotation,

Strategic Metallurgy Nickel

Strategic Metallurgy have demonstrated differential flotation techniques for Western Australian copper and nickel sulfide ores in saline water. Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficient, resulting in significant rejection of.

Processing Nickel Ores

The pyrrhotite is then sent to froth flotation cells, and produces a 3% nickel concentrate. The non magnetic ore is sent to a series of rougher, cleaner flotation cells, and produces a 31% copper concentrate. The tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with.

process called froth flotation. When air bubbles are introduced to the slurry, the minerals attach to the bubbles and float to the surface, where they are skimmed off. Both the nickel and copper float off together, and then the nickel is separated from the copper. The results of this are two distinct products: a nickel concentrate.
