Collectorless flotation can be demonstrated in plant practice, but there is usually little incentive to exploit as there is no easy way to determine if collectorless flotation will be robust to ore changes and collector addition removes that concern (Leroux et al., 1994).

Principles and practice of sulphide mineral flotation ...
This stone presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.

Flotation Reagents - Mineral Processing & Metallurgy. The most widely used sulphidizer is sodium sulphide, which is commonly used in the flotation of lead carbonate ores and also slightly tarnished sulphides such as pyrite and galena In the sulphidization of ores containing precious metals careful control must be exercised as in some instances ...
The effect of non-sulphide gangue minerals on the ...
To test the research hypothesis in the present study, varying amounts of gangue minerals were added to the isolated sulphides fraction and the flotation characteristics of sulphides was investigated to evaluate the effect of non sulphide gangue minerals on the flotation recovery and selectivity of the ore.
Flotation Reagents - Mineral Processing & Metallurgy
Consequently, aside from a few fundamental principles regarding flotation and the use of reagents, it is generally agreed each ore must be considered a problem for the metallurgist to solve before any attempt is made to go ahead with the selection and design of a flotation plant.
