In hydrometallurgical processes, nickel sulfide ores undergo flotation differential flotation if NiFe ratio is too low and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...

Selective flocculation can help to enhance flotation performance of laterite ore. Abstract. The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover nickel from laterite ores. Nickel in laterite ores is often finely disseminated in ...

Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods .

Jun 06, 2016 Its a shame that the highly depressed nickel market led to the cancellation of MEIs October Nickel and Cobalt Processing conference, as there are enormous challenges in the processing of nickel ores, particularly the laterites. The majority of the worlds nickel resources occur as laterite ores, which are complex, low grade, and expensive to treat using conventional smelting and
description of the processing steps used for the two types of ores. Lateritic ore processing Lateritic ores have a high percentage of free and combined moisture which must be removed. Drying removes fee moisture and chemically bound water is removed by a reduction furnace which also reduces the nickel
