In the Danchi mineralization belt of Guangxi province, south China, the Dachang tinpolymetallic ore deposit is one of the largest Sn ore deposits in this world. But about the genesis and the ore source, there have been some disputes. In terms of the Dafulou deposit, the mineralization model and deposit mechanism is rather illegibility. By analysing and comparing the lead isotope of three ore deposit (the Changpo, the Lamo and the Dafulou), it show that the correlations of 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb of sulfide minerals demonstrate obvious excellent linear relation. So, it is also suggested that the eastern mineralization belt, the middle mineralization belt and the western mineralization belt shared the same ore source. And, according to the features of no.22 ore body, the Dafulou deposit is characterized with the characteristics of the Sedimentary Exhalative Deposit (SEDEX). © (2012) Trans Tech Publications, Switzerland.

The influence of polyacrylamide (PAM) conditioning combined with Al2(SO4)3 coagulant on Tongkeng mine slurry dewatering behavior was investigated by capillary water absorption time (CST) measurements. The dependence of the slurry dewatering behavior on interval time of adding chemicals, stirring time, stir intensity, total dosage of chemicals, and chemicals ratio were analyzed in detail. When adding PAM alone in the slurry, the CST reaches its minimum value of 17.4 s at the PAM dosage of 3 mg·g-1. But when simultaneously adding Al2(SO4)3 coagulant and 3 mg·g-1 PAM in the slurry, the CST decreases to 16.9 s at the Al2(SO4)3 dosage of 1.5 ·g-1. The appropriate operating conditions were experimentally determined as the interval time of adding chemicals of 45 s, the stirring time of 120 s, and the stirring intensity of 40 r·min-1. By means of orthogonal experiment design, the significance of parameters influencing the slurry dewatering behavior is in the order of total dosage of chemicals > chemicals ratios, and the optimal total dosage of chemicals is 4 mg·g-1, with the mass ratio of PAM and Al2(SO4)3 of 1:3.

A new permanent magnetic separator was introduced to treat the ores with the characteristics of weak magnetic iron minerals and in a fine size range. The new machine was applied to the iron removal from potash feldspar. The effects of the magnetic field intensity,pulp density and grinding fineness on the iron removal were investigated. The optimized operation parameters were achieved and listed as follows: the -0.074 mm content is 85%, the pulp density is 45% and the magnetic field strength is 2T. A close test of middles regrinding was also carried out to improve concentrate yield. The data show that the grade of TFe(total iron) in potash feldspar product decreased from 1.31% to 0.21% and the concentrate yield reached 85.32%. All the results indicated that the traditonal high-intensity electromagnetic separators can be betterly substituted by the new permanent magnetic separator. This study may provide the theoretical evidence for iron removal from potash feldspar. © Wuhan University of Technology and SpringerVerlag Berlin Heidelberg 2013. Source

According to quality of raw water from tongkeng mine, analyzed the factors in the process of coagulation-sediment-filter on the Zn2+ions removal effect in wastewater treatment. Based on static test results, take the dynamic tests on water quantity, dosage of PAC and PAM, dosing way etc. The results show that through experimental parameters optimization, the removal rate can achieve 90.25% by the process of coagulation- sediment-filter to treat mine water with Zn2+ions. The effluent quality can satisfy national integrated wastewater discharge standard requirement. © 2011 IEEE. Source

According to the characteristics of mine water from Tongkeng, the heavy metal Zn2+ions in wastewater will be removed by composite flocculation. Through the experimental study on composite flocculation factors, containing drug types, drug ratio, drug time, pH value, stir time and stir intensity, analyzed the factors on the Zn2+ions removal effect in wastewater treatment. The results show that through experimental parameters optimization, the removal rate can achieve 97% by the application of composite flocculation to treat mine water with Zn2+ions. The effluent quality can satisfy national integrated wastewater discharge standard requirement. © 2011 IEEE. Source
