Case Study:Advantages of High Rate Thickening at TISCO Jianshan Iron Mine
Often plans to increase plant throughput provide an opportunity for optimising plant equipment and operating methods.This was the case in 2005 at TISCO Jianshan Iron Mine,when an increase in production was planned.The thickening circuit had presented a limitation to the plant throughput and operation with poor overflow clarity and underflow density.Following a course of test work by Outotec,a 53m diameter Supaflo(R) High Rate Thickener (HRT) was selected for the duty.From early stages of operation of the new thickener,the benefits have been dramatic,including: · Improved tailings underflow density by 9% · Improved Overflow clarity to less than 150ppm · Considerably decreased the water and energy consumption as well as operation cost · Stable and reliable operationThis paper looks at this installation as a case study and compares the previous thickener installation performance with the performance of the single 53m HRT.
