3.1.5 oxidation and reduction of laterite nickel ores. outotec has developed a process for the oxidation and reduction of laterite nickel ores where the reduction of iron and nickel to the wuestite/metallic states respectively is performed in a fluidized-bed reactor using reduction gas generated very cost-effectively from natural gas in an
laterite is one of the resources in astroneer. it is mined from red-and-blue cylindrical crystal deposits and can be refined in the smelting furnace to produce aluminum. laterite can be found on all planets typically underground in caves. source [edit edit source] laterite can be found on all of the planets.
nickel is found in two types of deposits; nickel laterites and magmatic sulfide deposits. although nickel laterites make up 70% of the world’s nickel reserves few of them become producing mines. over the last 60 years magmatic sulfide nickel deposits produced 60% of the world’s nickel. in the
laterite soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. it forms in tropical and subtropical regions where the climate is humid. lateritic soils may contain clay minerals; but they tend to be silica-poor
lateritic nickel ore deposits are surficial weathered rinds formed on ultramafic rocks. they account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel. genesis and types of nickel laterites. lateritic nickel
the down side to laterite ores and the reason why they haven’t been exploited on a widespread scale thus far is that they require much more energy in processing over sulfide ore types. lateritic nickel ore processing. while sulfide nickel ores are processed via upgrading to concentrates and then smelting this approach is not applicable to
