Abstract
Froth flotation is the most successful method of beneficiating mineral fines. The process is carried out in completely stirred vessels known as flotation cells. It was recently found that countercurrently operated flotation columns, with air bubbles uprising through downflowing slurry, show a definite potential to efficient and selective separation of fine particles. This report presents details and results from a research program that was directed toward understanding the principles governing the column flotation. Influence from a number of process variables was studied by using mixtures of finely ground dolomite and quartz. The column response was determined in terms of (1) recovery and grade of dolomite in the concentrate, and (2) holdup and solids concentration profiles within the column. The report includes a comprehensive analysis of the experimental results and the column flotation process.
