Under the best conditions, while the cyclojet cell reduced the iron-oxide content in silica sand from 0.41% to 0.08%, the conventional cell reduced it to 0.10%. While iron removal efficiency was 80.49% for the cyclojet flotation, it was calculated as 75.61% for the conventional cell. These findings showed that cyclojet flotation can be used as ...Web
