METHOD FOR NICKEL CONCENTRATION

1. A method for nickel concentration processing of a saprolite ore, characterized by comprising the steps of the following (1) to (4). (1) a saprolite ore is subjected to crushing processing to adjust the ore particle size to a size passing a sieve with an mesh opening of 50 mm. (2) a crushed ore obtained in the step of the above (1) is subjected to dry-type grinding processing of the surface

Nickel mining in Australia history, top locations and

2021-2-15  Nickel ore grades in the 1960s had 4% nickel but within a decade the nickel ore grade in Australia fell to 2%. Over the last 20 years, low grade laterite or sulphide deposits have posted an average ore grade of about 1.2%. Magmatic nickel-copper sulfide

ESG and Nickel Wading Through the Issues

The benefit of treating a laterite ore pyrometallurgically is that you utilise a greater percentage of the resource as the iron and nickel become a product, by way of example for 1,000,000 tonnes of ore mined, you might make 300,000 tonnes of product with a nickel grade of 6-10%.
