The water network synthesis of Sb recovery from lead anode slime with high antimony and low silver content using chloridization-leaching was analyzed. A superstructure was firstly proposed for the water network synthesis, based on which, an non-linear program (NLP) model considering both the waste minimization and Sb recovery profit was developed. Besides the traditional mass balance, the chemical reactions were also included. The model parameters were determined based on experimental data of real process. The optimal results are obtained with an improvement of 87.4% reusable water. Discussions on the flowsheet with optimal structure were also presented. Source

A new scientific proposition of synergetic mining was put forward by introducing the concept of synergism based on the current harmonic mining concepts. The clear definition and its significance of synergetic mining were given, and its technology system was built too. The difference and connection of the synergetic mining and the concepts and its coupling property were analyzed. Taking the mining of cataclastic resource with the many cavities in a certain mine as an example, the application of synergetic mining technology was studied. The mining environment reconstructing layering and stripping medium-length hole caving mining method was developed. The synergetic mining schemes design for the main ore layers were accomplished well. The application results show that synergetic mining as a new mining mode with strong vitality and great value of application can provide a scientific and suitable development direction for hidden danger resources or those deposits with special engineering purposes.

This paper mainly studied the removal of metal ions in wastewater from a mine. On the research basis of using traditional coagulation-sedimentation process to remove metal ions, this study took Zn and Cd ions as major research targets, and conducted the research of advanced treatment of mining wastewater. Enhanced coagulation and enhanced ion exchange process was adopted, and water quality indexes after treatment reach the national third class standard of surface water quality. © (2013) Trans Tech Publications, Switzerland.

A novel treatment process of lead anode slime bearing high antimony and low silver was developed by a potential-controlled chloridization leaching and continuous distillation. The experimental results show a high Sb3+ concentration, 489.2 g/L, in the leaching solution for two-stage countercurrent leaching process, and the leaching rates of Sb, Cu, Bi more than 99 when the potential is controlled at 450 mV. When the leaching solution is distillated and concentrated at 120 °C, almost all the silicon compound is evaporated into the concentration distillate and exists as amorphous hydrated silica. By the continuous distillation, high pure SbCl3 could be prepared, and AsCl3 is enriched in the distillate while metals Bi, Cu are enriched in the continuous distillation residue. As a result, the recovery rate of Sb is more than 95. © 2010 The Nonferrous Metals Society of China. Source

Monoclinic Li 3V 2(PO 4) 3 was synthesized by a microwave method. The influence of sintering temperatures and time on the synthesis of Li 3V 2(PO 4) 3 was investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and charge-discharge test. The results of these tests shows that the Li 3V 2(PO 4) 3 sample synthesized at 850 °C for 15 min has pure and perfect crystal. The charge-discharge test shows the Li 3V 2(PO 4) 3 sample with optimal synthesis condition has the best initial discharge capacity of 120 mAh/g, with capacity retention of 101 mAh/g after 50 cycles, in the voltage range of 3.0 V-4.2 V. © (2012) Trans Tech Publications, Switzerland.
