Highlights: Metallurgical testing confirms excellent nickel recovery of 46% and 51% from two locked cycle tests Conventional flowsheet employed with two stages of grinding, desliming, flotation .
Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficient, resulting in significant rejection of copper units to the nickel circuit.In Strategic Metallurgy’s experience, this alternative method is robust, easy to control and results in improved grade .
In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation .Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies .
It is recovered by first producing a flotation concentrate, then smelting and converting it to molten nickel-copper-cobalt sulfide matte.This is then solidified and leached using chlorine in hydrochloric acid, or using air in ammonia solutions, or using oxygen in sulfuric acid and producing cobalt metal by electrowinning or hydrogen reduction .
It was found that copper sulphate had an adverse effect on flotation performance when the flotation feeds were prepared in the laboratory.
Jan 08, 2021 The copper concentrate, at 18% copper, also included 1.7 grams PGMs (platinum, palladium and gold), while the nickel concentrate, grading 6.In addition to the existing resource, there are multiple additional target areas within the 146-sq.
Lime in Flotation and Recovery Processes Both quicklime and hydrated lime are widely used in the flotation or recovery of non-ferrous metals, including copper, zinc, nickel and lead-bearing ores.Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution.

( Nickel Creek or the Company ) is pleased to report the final results of its Phase II metallurgical program ( Phase II Metallurgical Program ) on the Nickel Sh w Project (the Project ) located in the Yukon, Canada.The Phase II Metallurgical Program succeeded in its primary objective of separating bulk CuNi concentrate into separate saleable nickel and copper .
Nickel response Figures 1 and 2 show how nickel cumulative recovery and grade varied with time during the flotation for the varying dosages of the copper sulphate added to the pulp.The overall consideration shows that at 15 g/ton copper sulphate dosage, nickel recovery improved clearly by a maximum of about 6 % without grade compromise.
