| Abstract: |
| Recovery of fine-grained wolframite is very difficult. In order to achieve the efficient recovery of fine-grained wolframite, the flotation separation behavior mechanism of wolframite and different types of garnet ore was studied , providing a flotation separation scheme for wolframite and different types of garnet ore. The pH test、collector dosage test、 metal ion dosage test 、depressant dosage test 、the adsorption amount of agent measurement、infrared spectrum analysis were carried out on wolframite and three different types of garnet ores. The results showed that the recovery of wolframite could reach 90.55% ,at pH=8,、250mg/L of benzohydroxamic acid,、10mg/L of Pb(NO3)2 、100mg/L of sodium silicate. The recovery of three different types of garnet ores was only 16.11%、7.80% 、4.95%. The effective separation of wolframite from three different types of garnet ores was achieved. The mechanism study shows that benzohydroxamic acid chemically adsorbed on wolframite and three different types of garnet ores. Pb(NO3)2 can promote the adsorption of benzohydroxamic acid on wolframite and three different types of garnet ores. Sodium silicate has no effect on the flotation of wolframite, but strongly inhibits the flotation of three different types of garnet ores. |
