PROCESSING METHOD FOR OXIDIZED NICKEL ORE Russian patent published in 2023 - IPC C22B23/00 C22B1/00 C22B3/08 H05B6/64 

FIELD: metallurgy.

SUBSTANCE: invention relates to the extraction of nickel from oxidized nickel ores. Processing of oxidized nickel ore includes obtaining a reaction mixture, processing the reaction mixture in a microwave oven and leaching of nickel from the product of processing the reaction mixture in a microwave oven. To obtain the reaction mixture, the ore is mixed with sulphuric acid and water. The reaction mixture is processed in a microwave oven and at the same time nickel is leached from the processing products in the microwave oven in a reactor with a mechanical stirrer, while using a pump, the reaction mixture is circulated from the reactor with a mechanical stirrer through the microwave oven with return to the reactor.

EFFECT: method makes it possible to technologically simplify ore processing and speed up the nickel leaching process.
