| titleOfInvention | Beneficiation method for high-carbon refractory lead-zinc ore |
| abstract | The invention provides a beneficiation method of high-carbon refractory lead-zinc ore, which relates to the technical field of mineral processing and comprises the following steps: transferring the raw ore pulp into a flotation tank, and adding a carbonaceous capture agent into the raw ore pulp to carry out carbon-lead floatation and the like; heating the mixed concentrate obtained by the floatable operation of carbon lead and the like, heating the mixed concentrate to 65-75 ℃, and separating to obtain carbon concentrate and primary lead concentrate; adding a pH regulator into tailings of the floatable steps such as carbon lead to enable the pH value of the tailings of the floatable steps such as carbon lead to be 10-11, then respectively adding zinc sulfate, sodium sulfite, a lead mineral collecting agent ethidium and a foaming agent into the tailings, and obtaining lead rough concentrate through flotation; and (3) regrinding the lead rough concentrate, adding a pH regulator to enable the pH value of the lead rough concentrate to be 10-11, and adding sodium sulfite to obtain secondary lead concentrate. The beneficiation method for the high-carbon refractory lead-zinc ore has the advantages of low impurity content of flotation concentrate, simple operation, stable flow, strong adaptability, convenience for field management and the like. |
