Applying new approaches, methods, and technologies for the estimation of reserves can effectively improve the efficiency and accuracy of assessments of solid mineral resources. After analyzing the development of 3-D geoscience modeling technology (3-D GMT), this paper discusses the application of 3-D GMT for the estimation of solid mineral reserves, emphatically introducing its workflow and two key technologies, 3-D orebody surface modeling, and property modeling. Moreover, the paper analyzes the limitations of traditional methods, such as the section method and geological block method, and points out the advantages of 3-D GMT: building more accurate 3-D orebody models, expressing the internal inhomogeneous attributes of an orebody, reducing the potential for errors in the estimation of reserves, and implementing dynamic estimations of reserves. 展开更多

With the development of modern industry and the increase of human demand, it is increasingly important to prospect and exploit marine mineral resources. Based on the oceanic geological investigation references obtained from the regional geological surveying and mapping of China Sea (“Shantoufu, F 50” 1∶1 000 000) and on the data (“Marine Engineering Geological Investigation Project in the Pearl River Mouth basin in the South China Sea” 1∶200 000), the authors elaborate the grain size composition, mineral composition, mineral features and distribution pattern of the surface sediments in the sea at 114°-120°E and 20°-24°N. Moreover, the analysis of the regional solid state mineral resources in the coast of Fujian, Guangdong and the west of Taiwan, shows that the main resources include littoral/neritic placers, littoral/neritic sandy gravel and ferromanganese nodule (crust). In addition, the future focus should be on the placers and sandy gravels in this littoral area. 展开更多

Wollastonite, a mineral of wide industrial applications was synthesised from rice husk ash silica and limestone. A number of raw batches consisting of these starting materials, in 1:1 molar ratio, were heat treated to produce it through solid state reaction from 900℃ to 1300℃. The conducted reaction was monitored by XRD step by step. Amount of Wollastonite formed at every temperature was also studied to some extent. Analyses of the obtained data indicated that the target mineral formation was quite effective and almost proportional to a rise in temperature up to 1200℃. The results from both, XRD and chemical analysis were found in fair agreement with one another 展开更多
