In order to remove arsenic from the alkaline solution for reuse, the leaching slurry should be concentrated and filtered. The unit area of ​​concentration is 0.58~
The obtained alkaline solution contains As 2~
According to the results of the concentrate treatment research, the following processes are recommended, including: air jet grinding (milling the prepared product to a particle size of -15 microns), leaching with sodium hydroxide solution, adsorption cyanidation, and pre-existing products according to production. metallic gold and silver flow to the desorption, the basic repeated purification mother liquor for recycling or disposal (FIG. 2). Technical and economic calculations show that the cost of concentrate processing is 30% lower than the actual situation of MJI3 after arsenic removal .
The process can be tested on a large scale to solve the possibility of practical application.
