攀枝花残坡积钛砂矿远景资源量预测

攀西地区钛资源十分丰富，是理想的钛项目建设基地。目前原生矿床的利用已得到广泛重视，但对该区钛砂资源状况了解不深。通过用统计和曲线积分方法（并适当参考云南钛砂资源的资料）来确定调查区合理的钛砂矿边界品位，达到矿产资源的最优利用；以规则的取样投影图形代替水平投影，对传统的地质块段法储量估算进行了数学纠正以得到合理的估算参数，并对调查区钛砂资源进行了远景储量估算。通过调查，估算攀枝花地区钛砂334资源量约达336．177×10^4t：并据地质和工程因素划分了三级远景预测区，为进一步勘查该区钛砂资源状况提供了参考。

Review of tungsten resource reserves,tungsten concentrate production and tungsten beneficiation technology in China

Tungsten is a strategic metal that is widely used in various fields such as electron communication, aeronautics and astronautics, materials and chemical engineering, due to its special properties. China has the largest reserves of tungsten resources and the largest output of tungsten concentrate in the world, and plays a decisive role in the world tungsten market. In this work, firstly, the reserves and distribution characteristics of tungsten resources in China were summarized, and the production situation of tungsten concentrate in China was reviewed. Based on the gross domestic product per capita (GDP/capita), five different annual GDP growth rates were used to estimate China's tungsten concentrate production in the future. The estimation results suggested that if China's economy continues to grow at the current rate, the accumulative production of tungsten concentrate will exceed current reserves by approximately 2032. Then, from the aspects of process flow, beneficiation equipment and flotation reagents, the beneficiation technology development of different types of tungsten ore in China was also reviewed, including wolframite, scheelite and tungsten-bearing slime. Finally, taking several representative tungsten mines in China as examples, the classic beneficiation technology of different types of tungsten ores was elucidated in detail. Meanwhile, the development direction of tungsten beneficiation technology in the future was put forward, which was of great significance to maintain the superiority of tungsten resources in China.

Flotation of indium-beard marmatite from multi-metallic ore

Flotation of indium-beard marmatite from Dulong multi-metallic ore in Yunnan Province of China was studied to improve the grades and recoveries of zinc and indium of the zinc concentrate in Dulong concentration plant.The experimental results indicated that copper sulfate mixed with a chemical reagent X-1 as the activator in the marmatite flotation produced a much better beneficiation than copper sulfate alone,increasing the zinc and indium recoveries of 10% and 6%,respectively,while the concentrate grades remained unchanged.Also,the new activator acted well around pH 10,allowing large savings on lime consumption in the rnarmatite flotation.In addition,it has been found that a sufficient activated lime of activator with ore slurry in the flotation is needed to achieve good beneficiation of the marmatite ore.     

Corrosion behaviour of carbon steel,titanium and titanium alloy in simulated underground water in Beishan area preselected for nuclear waste repository in China

The groundwater will completely infiltrate to the surface of nuclear waste container after the closure of its deep geological disposal. Therefore, the corrosion behaviour of Q235 carbon steel, titanium and titanium alloy, which were the candidates as the container materials for high-level nuclear waste disposal in simulated groundwater solution of Beishan to be served as the preselected high-level nuclear waste disposal area in China at different temperatures, was studied through electrochemical methods including open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarisation curve measurements. The results show that the corrosion rate of titanium and titanium alloy is lower than that of carbon steel at all temperatures, and they are more promising as container materials. Another phenomenon is that higher temperatures facilitate the protection performance of corrosion products compared with lower temperatures.

Anodic Behavior of a Titanium–Aluminum Hybrid Electrode: Formation of Hydroxide-Oxide Compounds

The electrochemical behavior of a titanium–aluminum hybrid electrode in aqueous solutions of electrolytes containing halide ions (F^– and Cl^–) was studied. The effects of current density, solution composition, and ratio of the working surface area of titanium and aluminum on the anodic dissolution rate of a Ti?Al hybrid electrode and its electrochemical characteristics were revealed. The joint anodic dissolution of aluminum and titanium in the aqueous media under study made it possible to obtain precursors of the highly disperse oxide system Al₂O₃–TiO₂. Data of X-ray and electron-microscopic analysis confirmed the results obtained.
