The process has been developed and patented by Promeca Consulting and Norilsk Nickel in Finland for the recovery of nickel and cobalt from limonite, saprolite and mixed ores. It is a twostage countercurrent atmospheric leach process using sulphur dioxide and concentrated sulphuric acid. The first step involves a
The company said that the process enabled better use of all ore types within the Ravensthorpe resource, and the recovery of an additional 15,000t a year of nickel. The process downstream of the leaching circuit uses a Cawse flowsheet with partial neutralisation, followed by separation of the barren tailings from the nickelbearing solution, further impurity removal and precipitation of the MHP.

3/08/2021 · Producing metal by growing plants, or phytomining, has long been tipped as an alternative, environmentallysustainable way to reshape – if not replace – the mining industry. Of 320,000 ...
Mill Process Description. Clarabelle Mill accepts nickelcopper ore from various sources and companies and produces a nickelcopper concentrate and copper concentrate for further processing. The ore is delivered via rail or truck to the facility where it undergoes primary screening. The screened ore is then conveyed to the Crushing Plant.
The stack of ore is then reclaimed and conveyed onto a secondary heap for final leaching. Bioleaching is an energyefficient way of producing nickel, for example. On the whole, the greenhouse gas emissions of the nickel production process are around 40%, sulphur dioxide emissions 2% and energy consumption 20% lower than average.

Boliden Harjavalta is loed in south west Finland, close to the port on the Baltic Sea. The smelter's main products are copper, nickel, gold and silver, as well as byproducts such as sulphuric acid. Boliden Harjavalta is unique – our smelter is the only nickel smelter in Western Europe.
It is based on the mining and processing of lateritic ore for the production of up to 40,000t/y of nickel and 2,500t/y of cobalt briquettes with a design cash cost of –/lb of nickel, making it one of the world's largest and lowestcost nickel producers. Stage 1 of the project was commissioned in 1999 at a cost of A1,030m.
This process, called the "leach cycle," generally takes from one or two months for simple oxide ores ( most gold ores) to two years for nickel laterite ores. The leach solution containing the dissolved minerals is then collected, treated in a process plant to recover the target mineral and in some cases precipitate other minerals, and recycled to the heap after reagent levels are adjusted.
