Abstract
This paper introduces improvement of the testing method of free silica in phosphate dissolving limestone,using hot phosphoric acid to dissolve ore and fluoboric acid to depolymerize molten silicate.Then,wash the precipitation heat with sodium hydroxide solution to make free silica seperate from other minerals,and measure them by the weight method.关键词
