Embodiment Construction
[0017] see figure 1 , a quartz sand flotation process, is characterized in that: the quartz sand raw material is loaded into the production silo by the loader, and then the quartz sand raw material is sent into the mixing impeller by the electronic belt feeder and the belt conveyor. In the first mixing tank, a permanent magnet is placed outside the first mixing tank. Before the quartz sand raw material is sent into the first mixing tank, the first step of iron removal is carried out by the permanent magnet. The first mixing tank is added with 4 -5%H 2 SO 4 solution or 4-5% H 2 SO 4 and HF solution, adjust the PH value in the first mixing tank to 3, and send the quartz sand raw material to form a quartz sand slurry; then send the quartz sand slurry into the second mixing tank that has been treated with the mixing impeller. At the same time, add the flotation agent to the second mixing tank for stirring, so that the quartz sand slurry and the flotation agent fully react unti...
