Quality improvement of copper concentrates by column

Detailed laboratory column flotation tests were conducted to improve the quality of copper concentrate at Malanjkhand Copper Project (MCP) of Hindusthan Copper Limited (HCL). Amenability of column as cleaner was studied on the rougher concentrates of lean and typical copper ores. Effect of column parameters viz. air flow rate, feed flow rate and column height were studied in addition to usual,(PDF) Development of indigenous column flotation,,Development of indigenous column flotation technology at NML for the beneficiation of low-grade ores.

BENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW

COLUMN FLOTATION . During 19 th century, various industries not used column flotation for the mineral processing. But there was drastic changes happened and around 1990 this method was going to more popular. (Dobby and Finch 1991, 1995., Bouchand and Desbiens 2009). The column flotation cells is the lack of agitation of column floatation which reduces energy and maintenance costs, this isBENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW,,Column flotation for the expansion of the flotation circuit at Samarco Mineracao, Brazil.
