Technical Field
The invention relates to purification of mineral wastewater, in particular to a slag recovery circulating water purification adsorbent and a preparation method thereof.
Background
A large amount of water is needed in the recovery process of valuable metals in the gold ore smelting waste slag, and although zero emission is realized to a great extent at present, the circulating water still needs to be replaced regularly. The replaced circulating water contains a certain amount of metal or mineral particles, but the content is low, and the metal or mineral particles are not enough to be recovered by large-scale mechanical equipment.
Disclosure of Invention
The invention provides a slag recovery circulating water purification adsorbent and a preparation method thereof, aiming at the problem of low purification efficiency of smelting circulating water by adopting mechanical equipment.
The technical scheme for solving the technical problems is as follows: the slag recovery circulating water purification adsorbent comprises the following components in parts by weight: 45-60 parts of polyacrylic resin, 30-60 parts of emulsion, 15-25 parts of nano particles, 0.5-1.5 parts of carbon black, 2-6 parts of thickening agent and 20-40 parts of deionized water.
Specifically, the emulsion is one or a combination of more of styrene-acrylate emulsion, acrylic emulsion or aqueous polyurethane emulsion; the nano particles are selected from one or more of nano magnesium oxide, nano magnesium hydroxide, nano zinc oxide or nano aluminum oxide; the thickening agent is one or more of starch, gelatin or CMC.
The invention also discloses a preparation method of the slag recycling circulating water purification adsorbent, which comprises the following steps: weighing the components according to the weight percentage, grinding and filtering the polyacrylic resin, mixing the ground polyacrylic resin with the nano particles, adding the mixture into emulsion, adding deionized water while stirring, adding carbon black and a thickening agent after continuously stirring uniformly, pouring the mixed solution into a strip-shaped mold after uniformly stirring, drying, demolding, and wrapping a blank mold with a metal wire mesh to obtain the coating.
The invention has the beneficial effects that: the slag recovery circulating water purification adsorbent can effectively adsorb metal or mineral particles remained in slag recovery circulating water; prepared into strips, and can avoid the diffusion of the adsorbent after being wrapped by a wire mesh, thereby being beneficial to the recovery.
