It belongs to the field of mineral processing technology, suitable for mineral processing of polymetallic ore containing niobium-titanium uranium ore, and specifically relates to a polymetallic ore processing process containing niobium-titanium uranium ore; The invention is to economically develop and utilize a low grade polymetallic ore containing niobium-titanium uranium ore, and the process of the invention relates to a combined process flow of gravity separation, magnetic separation and flotation. First of all, the ore is grated and classified after gravity separation, and then the gravity separation concentrate is reground and flotation of sulfide ore and magnetic separation of iron ore can get sulfide ore concentrate and iron concentrate; Secondly, uranium concentrate of high grade and high recovery can be obtained by adding high efficiency collector and direct flotation technology of uranium ore of niobium-titanium-uranium. The processing capacity of uranium concentrate in subsequent hydrometallurgy process can be greatly reduced to extract uranium, greatly reduce hydrometallurgy cost and significantly improve economic benefits; Through beneficiation, sulfide ore and iron minerals can be recovered synthetically, and other associated useful components, make full use of resources.
The paper provides a kind of polymetallic ore dressing process containing niobium-titanium uranium ore, reduces the subsequent hydrometallurgy cost, and solves the existing technology using reverse flotation gangue minerals such as sulfate minerals and carbonate minerals, because of the poor selectivity of the collector used, is not beneficial to the flotation separation between minerals, it is difficult to get high grade uranium concentrate.
Kind of titanium niobium containing polymetallic ore dressing technology of uranium ore uranium grade 0.03% titanium niobium uranium after the re-election, uranium grade of 0.128% can be obtained, the uranium recovery 77% of heavy concentrate, re-election concentrate after grinding and flotation sulphide ore minerals and magnetic iron after uranium grade can be increased to 0.154%, again through the flotation recovery of uranium, uranium ore concentrate grade of 1.12%, can be obtained The rate of fine mineral is 1.89%, the flotation recovery is 92.69% and the total recovery of uranium is 70.56%. The processing capacity of uranium concentrate in subsequent hydrometallurgy process can be greatly reduced, the hydrometallurgy cost can be greatly reduced, and the economic benefit can be significantly improved.
