| Abstract: | The aim of this work is carrying out dressing investigation on a low grade refractory sludge in Yunnan Tin Corporation. Based on the properties of the ore, a process routed as enrichment and de-sludge by pre-separation with centrifugal, floatation for removal sulfides, cassiterite floating was employed to recovery effectively cassiterite with fine grain in the sludge. Results indicate that good index is obtained. Which the grade of tin in concentrate reaches 6%, recovery efficiency in sludge system reaches 40.43%, and recovery efficiency of cassiterite floating reaches 76.28% while the tin grade of charging ore is 0.21%. |
