dc.description.abstract |
Air Table it is a tool based on the mineral concentration of gravity concentration. Style-style that works on the tables of the air is the force of gravity, friction and thrust media (influenced by air is exhaled at the table). A problem that often occurs is yet to achieve increased levels of 70% Sn which is caused by variable tool on the table to air. Based on these problems, then the goal in this research are as follows: (1) to know the process of processing the ore of Tin in Tin Ore Processing Center Pemali. (2) to get the rate of bait, setting the interval measure hopper and a splitter on the optimum table air in achieving levels of cassiterite 70% Sn (3) to find out the correlation between the rate of bait, the interval measure hopper and splitter to increased levels of the mineral cassiterite. (4) to find out the most influential variables between the rate of bait, the interval measure hopper and splitter to increased levels of the mineral cassiterite. The procedure of this research include: the study of literature, observation, data retrieval, processing and analysis of data. The results of this study are: (1) processing of tin ore in Pemali Tin Ore Processing Center is done with 2 (two) process: wet processing and dry processing. (2) obtained by setting the splitter cassiterite range 0.2-1.1 cm, splitter tailings range 0.5-2 cm, the rate of bait 873 kg/h and measuring hose hopper 70 º able to produce cassiterite with 70% Sn (3) there is a positive relationship between the rate of bait against levels of cassiterite which included the criteria is very strong, there is a positive relationship between the interval of measuring hopper towards the levels of cassiterite which included the criteria is very strong and there is a negative relationship between splitter against the levels of cassiterite which included enough criteria. (4) obtained as 1 (one) the most influential variables against levels of cassiterite value-based significance is the interval of measuring hopper. |
