Ore separators carries out gravity treatment to particulate antimony oxide ore ore pulp, obtains heavy mineral ore pulp and tailing, and it is de- that heavy mineral ore pulp is carried out centrifugation
Water, obtaining mass concentration is ore pulp after the sizing mixing of 34wt%, and ore pulp after sizing mixing in mass ratio: plumbi nitras=100000:20 is added
Plumbi nitras stirs 2-6min, obtains the activation ore pulp that pH value is 7.8, is then based on ore pulp after 100000g sizes mixing and 40g is added
RCOONa and 2g terpenic oil, stirs 2-6min, and flotation 3-10min obtains antimony rough concentrate.The antimony rough concentrate is through one roughing, secondary
It scans and obtains the antimony concentrate that grade is 28.10%, antimony recovery 51.50%, with existing re-selection procedure 10% with recleaning
The rate of recovery compare, the rate of recovery improves 40.50%.
