[0023] See attached figure 1 , the recovery method of a kind of sapphire polishing waste liquid that the present invention provides, polishing waste liquid comprises diamond particles, resin copper shavings, sapphire shavings, dispersant, because in the polishing process, copper plate wears out faster, causes the resin in polishing waste liquid Copper shavings and metal copper shavings account for a higher proportion than other components, and they also have a certain recovery value. Based on the differences in the characteristics of the components contained in the polishing waste liquid, the processes of vibrating screening, chemical separation, and electroplating separation are used respectively. For example, include the steps:
[0024] S1 collects the waste slurry, and adds water equivalent to more than 3 times of the waste slurry, and the multiple used in this embodiment is 4;
[0025] S2 Ultrasonic dispersion of waste slurry particles is carried out by ultrasonic waves w...
