Dispersion-Selective Flocculation-Desliming Characteristics of Oxidized Taconites

摘要

The Bureau of Mines undertook a bench-scale study of three different types of oxidized taconites from the Lake Superior district to improve the dispersion-selective flocculation-desliming process for beneficiating these materials. The response-surface contours of the effects of dissolved ionic species in the water and of three dispersion systems on the selective flocculation process were studied. Results of metallurgical data and chemical analyses of the aqueous phase showed that the water quality affects the performance of the selective flocculation process.
