Nickel

Nickel is most frequently found in sulfidic ores and nearly always mixed with copper, cobalt, zinc, iron, and other metals While solvent extraction (SX) can be used to recover nickel, novel selective ion exchange (IX) resins are making it possible to isolate and purify nickel at lower cost and in more environmentally sustainable ways.

Potential for cobalt recovery from lateritic ores in Europe

Co-bearing nickel laterite ores being mined in Greece, Macedonia and Kosovo where the cobalt is currently not being recovered (ores have typical analyses of 0055% Co and >1% Ni,) These ores are currently treated directly in pyrometallurgical plants to recover the contained nickel and this process means there is no separate cobalt product.

Cobalt Recovery from Waste Catalysts (Petroleum Refining

Recovery of cobalt, nickel, and copper from slags, using

Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DC-arc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining the maximum possible quantity of iron as oxide in the slag.

Effect of thermal pretreatment on recovery of nickel and

Abstract Experimental investigation made previously on microbiological leaching of nickel and cobalt from the laterite nickel ore of Sukinda Valley reveals that the recovery was not very much promising under any favorable conditions.

Cobalt extraction

Recovery from laterite or Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore The hydrometallurgical process for laterite.

The nickel laterite challenge

Jun 21, 2012· The issue of recovery of the value metals, nickel and cobalt from the solution remains This includes post major impurity (mainly iron) removal.

Pre-Reducing Process Kinetics to Recover Metals from

The main problem of the separation process from nickel mining using the ion exchange technique is the presence of iron, which precipitates in pH above 200 and causes coprecipitation of copper and cobalt Chelating resins have the main advantage of being selected for a specific metal present in solution Studies have been developed to increase the efficiency of metals recovery using chemical.

Nickel and Cobalt

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 non-value sulfide minerals.

Cobalt

Cobalt lies between iron and nickel on the Periodic Table and its smelting behavior also falls between that of iron and nickel For example, cobalt tends to oxidize more than nickel but less than iron The economic result of this observation for smelting is that the recovery of cobalt to matte is always less than the recovery of nickel to matte.
