METHOD OF DEPRESSING READILY FLOATABLE SILICATE MATERIALS |
摘要 |
<p>The invention resides in the use of a bacterial cellulose as a depressant for readily flotatable silicate minerals in an ore flotation process. Depending on the particular ore being treated, from 0.2-1.5 lb/ton of ore of the bacterial cellulose is effective as a talcose mineral depressant. Usually only about 0.10-0.25 lb/ton of the bacterial cellulose will produce optimum results. <IMAGE></p> |
