【摘要】 选择浙江有代表性的淳安、湖州、诸暨三地的三种花岗岩,用浮选法对其中长石与石英进行分离试验,取得了较好的效果:长石精矿的K₂O+Na₂O含量提高到11.78～12.75%,铁含量降低到0.28～0.39%,可作为陶瓷、玻璃工业的原料。更多还原

【Abstract】 Granite is marly composed of feldspar, quartz and a little of ferro-minerals. The feldspar is indispensable material for the industry of Porcelain and Glass. The authous, chose 3 typical kinds of granites from chun’ an, HuZhou, Zhuji in Zhejiang province to do experiment of separating feldspar and quartz through floatation process. The results are satisfactory. The. composition of K₂O+Na₂O in refined feldspar in improved to 11.78-12.75%, and the composition of iron reduced to 0. 28-0. 39%. It can be used as the material of the porcelain and glass industries.更多还原
