The flotation of pyrite using xanthate collecters [PDF]

open access: yes, 1986
Bibliography: leaves 117-123.The flotation properties of pyrite were found to be significantly influenced by variations in the pH. In acidic solutions the pyrite floatability is very high, and recoveries of 95% could be achieved using only a frother.

Effect of desliming on the flotation of a complax copper ore from China

open access: yesMATEC Web of Conferences, 2016
The complex copper oxide ore sample was taken from Deerni copper deposit, Qinghai Province of China. Batch flotation tests had been conducted to upgrade the copper concentrate by conventional amyl xanthate reagents under 73% -74 μm of the particle size ...

Efficacy of sustainable polymers to mitigate the negative effects of anisotropic clay minerals in flotation and dewatering operations

open access: yesCleaner Engineering and Technology, 2022
The depletion of high-grade ore resources and ongoing demand for mineral products has led to an increase in the exploitation of low-grade and complex ores, which often contain colloid clay particles (e.g., kaolinite) that are detrimental to flotation and

A Study of the Functions of Flotation Reagents in the Soap Flotation of Chalcopyrite

open access: yesFLOTATION, 1955
This work consists of (I) a study of the flotative properties of chalcopyrite in a nearly pure state, and (II) the application of the experimental information to concentrating low-grade chalcopyrite by flotation.(I) The experiments were performed with a 50-gram flotation machine of M. S. type, made of stainless steel.
