Due to high‐grade copper sulphide deposit exhaustion, the focus has now shifted towards recovery from different lean‐grade oxide and mixed ore deposits. The present paper …
Modified thionocarbamates are used in copper-gold ores, which allow some selectively against iron sulfides even at a pH value less than 10. Many gold plants use a blended collector or separate collectors as needed based on mineralogy and ore chemistry. Copper sulfate is commonly used as an activator of gold-bearing iron sulfides in flotation ...
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
coarse (500µm) particles, in contrast to other electrostatic separation processes that are typically limited to particles >75µm in size. STET has successfully beneficiated iron ore samples including run-of-mine ores, tailings and itabirite with …
