Keywords flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).

Flotation of a variety of nonsulphide and mixed sulphide plus nonsulphide copper ores is disclosed. Stabilization of nonsulphide copper mineral surfaces by sulphidization is initially required and a selective complexing agent able to complex with the copper sulphide surface is then added as conditioner. Diphenylguanidine proved to be a highly selective and fast acting surface conditioner

8/3/2018· Copper sulfide ore has better floatability than sphalerite, pyrite and another sulphide, so it is more likely to float from the pulp by adsorpting collecting agent. Therefore, flotation process is the main beneficiation method for copper sulfide ore.

Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickelbearing iron sulphides which report to the flotation tails.

Almost all copper sulphide ores contain ironbearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of copper sulfide from iron sulfide. Jul 01, 2019018332While flotation is a common method to concentrate sulphide ore in the DRC, oxide ore requires sulphidisation prior to flotation with xanthate collectors Crundwell et al.

1/11/2014· Other researchers such as Fornasiero et al. (2) and Byrne et al. (1995) also used preoxidation to separate copper sulphide minerals from arsenic minerals, but they found that arsenic minerals were more oxidised resulting in depression in the flotation of copper sulphide minerals.

From past reviews, the recovery of copper from sulphide mineral using xanthate and pine oil is relatively easy, but mixed oxidesulphide minerals do not respond to traditional sulphide collector. There is no common reagent to recover copper from both oxide and sulphide mineral, which is a great challenge in flotation of both the minerals simultaneously.
