J. Cent. South Univ. (2018) 25: 1306-1316 DOI: https://doi.org/10.1007/s11771-018-3827-3 Surface property variations in flotation performance of calcite particles under different grinding patterns... surface properties different from particles produced by other grinding patterns, which exert great influence on mineral flotation. Flotation performances of calcite particles under different grinding......
">The existence and release of fluid inclusions in bornite and its associated minerals,namely,quartz and calcite were investigated and confrmed.The structures,forms,and phases of these large quantities... of copper and iron released by fluid inclusions in the bornite sample is higher than the amount dissolved by the mineral;fluid inclusions in the associated gangue minerals,quartz,and calcite also make......
甘肃大水金矿床方解石的稀土元素地球化学特征代文军1,陈耀宇1,马小云1,史文全1(1.甘肃省兰州市甘肃省地矿局第三地质矿产勘查院)摘 要:方解石是大水金矿床脉石矿物之一,其形成贯穿整个成矿过程.根据野外观察和室内分析,大水金矿床中的方解石分为矿化期前,矿化期和矿化期后3期.通过对不同产出类型方解石稀土元素地球化学特征研究表明:不同产出类型的方解石稀土元素含量,有关参数和配分模式均有不同程度的差别,显示不同来源;矿床成矿流体具多来源特征.成矿环境表现为相对开放而氧化的环境.关键词:方解石; 稀土元素......
Trans. Nonferrous Met. Soc. China 22(2012) 1203-1208 Anisotropic surface broken bond properties and wettability of calcite and fluorite crystals GAO Zhi-yong, SUN Wei, HU Yue-hua, LIU Xiao-wen... different surfaces of calcite and three surfaces of fluorite were calculated. In terms of the calculated results, the commonly exposed surfaces of the two minerals were predicted and the relations......
their depressing effect on minerals containing Ca2+/Mg2+ gangues. Calcite, mixture of calcite and fluorite, and nickel ore were used in the flotation. And the depression mechanism was studied... exhibits strong depressing ability on calcite in almost zero yields at pH value of 9.8, and calcite can be depressed in the flotation of calcite/fluorite mixture for approximate 87% yield of fluorite......
on calcite FENG Qi-ming, ZHOU Qing-bo, ZHANG Guo-fan, LU Yi-ping, YANG Shao-yan (School of Mineral Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: The effect of sodium hexametaphosphate on the flotation of calcite and its surface properties was investigated by flotation test, IR spectroscopy, adsorptive capacity and ζ potential. The flotation result shows......
