The ore mineral assemblage of Dayishan wollastonite deposit is complex being composed of wollastonite, diopside, idocrase, K—feldspar, albite, calcite and quartz. To evaluate the ore deposit, it is necessary to determine the content of wallastonitt in the ore. The results from the petrographical study lack of representation. The paper has introduced the method of using the analytical data of chemical composition of the ore in conversion of the wollastonite content.

大义山硅灰石矿床矿石矿物组合复杂,由硅灰石、透辉石、符山石、钾长石、钠长石、方解石、石英等组成。矿床评价需要测定矿石中的硅灰石的含量。岩矿鉴定用薄片测定的结果缺乏代表性。本文介绍了用矿石化学成分分析数据换算成硅灰石含量的具体步骤。

The chemical weathering of manganese ores under dry climate condition is controlled by the fugacities of O_2, CO_2 and S_2 in the atmosphere and soil and the manganese minerals are occurred in solid phase transformation without migration of Mn and Fe elements. Manganese minerals of low valecy are not stable on the earth surface and easy to be oxidized into high valency manganese compounds which are stable and easy to form secondary high grade manganese ores. The manganese ores in carbonatite formation may be...

The chemical weathering of manganese ores under dry climate condition is controlled by the fugacities of O_2, CO_2 and S_2 in the atmosphere and soil and the manganese minerals are occurred in solid phase transformation without migration of Mn and Fe elements. Manganese minerals of low valecy are not stable on the earth surface and easy to be oxidized into high valency manganese compounds which are stable and easy to form secondary high grade manganese ores. The manganese ores in carbonatite formation may be secondarily enriched while those in clastic rock formation are easy to be migrated or washed away. This difference is a chief obstacle for manganese ore exploration.

干燥气候下,锰矿石的化学风化受大气和壤中O_2、CO_2、S_2逸度控制,锰矿物呈固相转变,不存在Mn、Fe元素迁移现象。热带、亚热带潮湿气候,低价锰矿物不稳定,地表易氧化成高价锰;高价锰矿物稳定,易形成次生富锰矿。碳酸盐建造中锰矿可次生富集,碎屑岩建造中锰矿易流失迁移。这种差异是锰矿找矿中的主要障碍。

The Dapo kaolin deposit in Guangdong province is of weathering residual type of granite. Kaolin ores have considerable reserves and possess good quality with, especially, very high natural whiteness; they therefore can be used as excellent materials for papermaking.

广东化州大坡高岭土矿属花岗岩风化残积型矿床,矿石矿物成分简单,以高岭石和石英为主,两者在粒级分布上差异明显,很易分选。精选后的高岭土中,高岭石含量可达91%,石英为1%以下。高岭石有序度较高,晶形规则,大多以叠片状和蠕虫状产出,但经机械处理后大部分可剥离成细小的高岭石单晶。矿石化学成分中Fe2O3,TiO2含量低,使高岭土具有较高的自然白度。造纸涂布试验表明高岭土的涂布性能良好,涂布纸具较高的平滑度,但涂料粘度偏高,这些性能和高岭石的矿物学特征有关。
