The method of smelting waste residue of fluoroaluminium
There is a technique now, which can smelt waste residue of fluoroaluminium. The first method of material selection is to distinguish the quality of the waste residue and clarify the composition it contains, so as to make good use of it.

At the beginning of the smelting, first put the waste residue in a purifier, wash it with water, and remove its dust impurities. After washing, drain the water and leave the waste residue for later use.

The second time is calcined by fire. Set up a furnace, adjust the heat moderately, and throw the waste residue into it. When calcining, people cannot leave, and they need to observe the level of the fire and observe the change of the waste residue. Wait for its color to change and quality to stop calcining.

After that, use medicine to melt it. Choose the appropriate agent, mix it with the waste residue after calcination according to the amount, put it in the kettle, stir it slowly, so that the agent and the waste residue are fully soluble. This process also needs to control the temperature, so as not to overheat or overcool, so as not to affect its dissolution.

After the dissolution is completed, filter it with a filter, remove the residue, and leave the clear liquid. The essence contained in the clear liquid is the essence of fluoroaluminum.

At the end, extract it by method. Or use distillation, or the technique of crystallization, so that fluoroaluminum precipitates from the clear liquid, and finally obtains a usable material.

This method of smelting fluoroaluminum waste residue needs to abide by the steps and observe the changes carefully.
