Transformer oil vs. kerosene: Selective collectors for C-matter
To improve gold recovery from gold ores containing C-matter, flotation was evaluated as a means to separate C-matter from the ore prior to POX, allowing the flotation concentrate and tailings to be treated by different processes: the C-matter concentrate could be sent to the limited capacity of Goldstrike roaster to decompose the C-matter, and ...

Flotation
Flotation is an extremely size sensitive process and because the RC drilling process imparts a lot of energy into the sample, the resulting fine particle size distribution is likely to be much finer than required. Also, the detergents used in RC drilling will very often react unfavorably in the flotation cell with other reagents.

Abstract The authors investigate a new reagent—modified water-soluble polymer of polyvinyl caprolactam (PVCL)—as a collector in flotation of gold-bearing sulfide ore. Modified PVCL is obtained by solid-phase modification of poly(N-vinyl caprolactam) by thiourea. The electron scan and laser microscopy identified adsorption of PVCL at gold grains applied …

Basic Principles & Variables Affecting Froth Flotation
The mineralogical character of the ore determines, in a way, the character of the principal flotation agent or "oil" to be used. From this statement it is not to be understood that for a given ore one and only one oil can be used or even, disregarding for the moment the commercial consideration of availability, can be best used.

Flotation of gold and gold-bearing ores
Early work on gold particles with copper sulfate showed no improvement in recovery but an increased rate of flotation of gold (Leaver and Woolf, 1934). More recent laboratory testwork on a refractory gold ore has shown, however, that a 5% increase in free gold flotation recovery is achievable when adding copper sulfate (Teague et al., 1999b).
