| The present embodiments generally relate to a technology for improving Cu/Mo grade by the addition of cationic polymers as selective depressants for acid insoluble matters, e.g., silicates and/or clays, in the flotation circuit. Various types of cationic polymers are demonstrated to be effective depressants including polyamine, polyDADMAC, and cationic polyacrylamide. Also disclosed are processes for enriching a desired mineral from an ore comprising the desired mineral and gangue, wherein the process comprises carrying out a flotation process in the presence of one or more cationic polymer depressants. | ||||||
| 280 | Amine Mining Collectors | US15299816 | 2016-10-21 | US10047044B2 | 2018-08-14 | Thomas P. Daly |
| A family of amine mining collectors that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency. | ||||||
