For flotation recovery of malachite, there are two general technologies, pre-sulfidization flotation with sulfydryl collectors such as xanthates and direct flotation with oxide mineral collectors including fatty acids, fatty amines, petroleum sulfonates and hydroxamic acids . In most cases, the former is more effective than the latter.

Today, a mixture of tall oil fatty acids and cresol has been successfully used for flotation of spodumene and phenacite 14. Table 2 shows some physical and chemical properties of phenol frothers. tion of oxide lead minerals. The following two structures are used as frothers 7. Fig. 6 shows the chemical formulas of these frothers.

This pH factor is modified with the help of the substances called pH MODIFIERS. Alkalinity in a solution is maintained by the addition of Lime, Sodium carbonate , and to a lesser extent NaOH and Ammonia . Sulphurous and Sulphuric acids are used to lower the pH. Lime is widely used in the form of Milk of Lime, to maintain the pulp alkalinity.
