SAMCO promises coke partner and customer satisfaction through our comprehensive, project-based approach coke delivers customized industrial solutions. Integer hendrerit, coke non coke posuere, orci nulla cursus erat, quis volutpat. Learn more about our base metal operations. As a global company, our developments have an impact at home and abroad.

Stay informed with the latest information from our press room. There is coke bright future for you at Vale. Learn more about the opportunities to grow your career with us. The nickel industry worldwide has traditionally smelted concentrates produced from nickel, copper and cobalt sulphide ores to make an intermediate sulphide product called matte. Hydrometallurgy has been used for refining the matte to produce high purity nickel, copper and cobalt coke the market.

Thus, traditional production of these metals has occurred in two steps: smelting and refining. The coke hydrometallurgical process that Vale developed will process the nickel concentrate directly to metal products without first having to coke the concentrate.

The concentrate will coke processed in coke pressurized vessel where it will react with oxygen and sulphuric acid to produce an impure solution of nickel, cobalt and copper.

This solution will pass through a number of chemical purification steps ending with removal of impurities coke separation of nickel, copper and cobalt. The copper and cobalt will be recovered as by-products.

The nickel will be recovered by electrolysis as high quality electronickel product suitable for market. The waste solids from the process will be neutralized with lime and will be deposited in a specially designed coke facility.

All water leaving coke plant, including precipitation run-off water, will be processed to remove contaminants. Because the hydromet process used coke Long Harbour eliminates the coke for smelting coke, it has an economic advantage over the traditional two-step smelting and refining process.

The process will also yield more of the valuable cobalt which is coke to a great extent in the smelting process. Coke type of hydrometallurgical process is not entirely new. Many operations, some of them in Canada, have used hydrometallurgical processes for years for extraction of zinc and copper from sulphide concentrates. However, it was not until coke 1990s that an acid-oxidative hydromet technology was developed to process nickel sulphide concentrates.

Vale is a global mining company, transforming natural resources into prosperity. Headquartered in Brazil and present in about 30 countries, we employ approximately 110,000 people between direct employees and permanent contractors.

The goal is to reduce the energy consumption of beneficiation processes (such as flotation coke leaching) with biotechnology, thus offering more cost-effective processes than external attribution. Microbes coke be used to reduce or even avoid using coke, which will coke influence not only processing costs but also the environment.

Our laboratory conducts bioleaching studies to separate coke from sulphide ores, for example. Studying the application of bioleaching coke various slag materials and industrial side products is one of our newest research areas. Geological Survey of Finland is a leading European competence center on the assessment coke sustainable use of geological resources. Geological Survey of Finland Vuorimiehentie 5 P.

We can conduct hydrometallurgical studies as batch studies or on a continuous coke.
