Tin ore beneficiation plant road tin cassiterite more than 5mm and less than 5mm in grain size distribution characteristics of money have some differences, therefore bounded 5mm thickness sorting.
Part of a large concentration of coarse brown tin-containing iron ore, with two grinding two sorting. The +5mm coarse sand was subjected to two jigging after the rod grinding, and the concentrate enrichment ratio was 61 times, and the operation recovery rate was 37%. The second jigging tailings were shaken with a shaker to obtain a coarse concentrate of 8% to 9% of tin grade into the second stage mill. The recovery rate of the coarse sand system was about 60%, and the recovery rate of the original ore was 20%. -5mm fine sand, graded with 600mm cyclone, its grit is selected by two jigging, the enrichment ratio can reach 45 times, the operation recovery rate is 43%~45%, and the overflow is repeated with 400mm. The flow class is classified and selected by a shaker. The recovery rate of the system is about 53%, and the recovery rate of the ore is 35% to 36%. The recovery rate of the middle mine into the second stage grinding and re-grinding operation is 18, which is 7% of the original ore.
The trapezoidal jigging in the process is a 250~1050*3300mm single row three-chamber trapezoidal jig.
