Embodiment Construction
[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] A kind of barium sulfate waste slag comprehensive utilization method, such as figure 1 shown, including the following steps:
[0028] (1) The newly produced barium sulfate slag is separated through a 5-mesh sieve, and the large particles that have not been burned through or the sintered symbionts that have not completely reacted in the barium slag are selected for peeling. At this time, the barium slag with larger particles accounts for 40%, and its barium sulfate content is about 35%.
[0029] After the large-grained barium slag is crushed and crushed, the particle size is controlled at 2-3 mm, and then it enters the jigging machine for jigging flotation, and a specific bed is selected according to the density of the recovered target object, and the bed particle size is controlled at 4-3 mm. Between 10mm (preferably 6-8mm), the bed t...
