Flotation Of Nickel
2. 2. flotation procedure all the flotation test-work was done using the denver laboratory machine with a 1.5l stainless steel flotation cell. the required mass of nickel-copper sulphide ore material ground to 70% passing 75 m was weighed and placed in the flotation cell. this was followed by the addition of distilled water to.4. magnetic separation-reverse flotation process. at present, the operation of magnetic separation (including weak magnetic separation and strong magnetic separation) is one of the effective means of throwing tails in advance; anion reverse flotation and cation reverse flotation are one of the effective means to improve the grade of iron.
