  • A New Process for Cobalt Nickel Separation - Teck

    A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.

  • Our Operation

    PT Vale produces nickel in matte, an intermediate product, from lateritic ores at our integrated mining and processing facilities near Sorowako on the island of Sulawesi. Our entire production is sold in US dollars under long-term contracts for refining in Japan.


    A further important use for electrodeposited nickel is electroforming. Nickel electroforming is the process by which nickel is built up by electrodeposition onto a suitable mandrel and subsequently removed to produce a nickel product which corresponds precisely to .

  • CDC - Nickel - NIOSH Workplace Safety and Health Topic

    Nickel (Ni) is a hard, silvery-white metal that may cause irritation to the skin. Exposure can harm the lungs, stomach, and kidneys. Exposure to nickel may lead to cancer. Workers may be harmed from exposure to nickel. The level of exposure depends upon the dose, duration, and work being done. Nickel is used in many industries.

  • A Guide to Working With Copper and Copper Alloys

    copper nickels are also used for pipes, valves and fittings in systems carrying potable water, process water or other aqueous fluids, and industrial gases. Copper alloys are also ideally suited where it is important to minimize bacterial* levels on touch surfaces.

  • Metal Toxicity: Health Dangers of Nickel

    Oct 09, 2015 · Nickel is widely used in industry, primarily refining, electroplating, and welding. The National Institute for Occupational Safety and Health warns that workers who inhale nickel laced dust and fumes are at an increased risk for lung cancer and fibrosis.

  • Sulfamate Nickel Plating Services (Company)| Mil-P-27418 ...

    Sulfamate nickel plating is an electrolytic plating process first developed by Piontellil and Cambri in 1938. The primary difference in the sulfamate nickel plating bath is the use of nickel sulfamate rather than the nickel sulfate as is used in the traditional Watts nickel plating solution developed by Oliver Watts in 1916.

  • High Quality (and Safe) Nickel Plating: 7 Steps (with ...

    Nickel plating can be used for a variety of different things. - It creates a corrosion resistant coating that will protect the base metal from oxidizing and rusting. It is frequently used in food processing to prevent contamination with iron. - It can increase the hardness and thus .

  • What is a Nickel Plating? - Definition from Corrosionpedia

    Nickel is also used as an under-plate for other metals such as gold and silver because it acts as a diffusion barrier that prevents any form of substrate migration to the top coating. Parts processed with a bright nickel plating layer maintain their surface appearance and brightness over time.

  • Nickel - Wikipedia

    Nickel. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site .
