非金属矿物常见选矿提纯方法、原理及主要工艺设备
对于非金属矿来说，纯度在很多情况下指其矿物组成，而非化学组成。有许多非金属矿的化学成分基本相近，但矿物组成和结构相去甚远，因此其功能或应用性 (1)菱镁矿选矿提纯方法 目前主要运用浮选法和化学选矿等方法提纯菱镁矿。 浮选法：菱镁矿中的杂质可分为硅酸盐和碳酸盐两类，通常根据其杂质类型确定浮选 我国菱镁矿选矿提纯工艺及产业现状！__矿道网

菱镁矿浮选工艺
菱镁矿浮选工艺 破碎和研磨工艺. 破碎：原矿（小于200mm）经过包括颚式破碎机和振动筛的两段闭路过程，将矿石破碎至10~0mm。. 研磨：将破碎的矿石进行闭路研磨，将矿石研磨至-200mm 70%，然后进入浮选过程;菱镁矿选矿的目的是除去其有害杂质和提高矿石品级，主要是解决硅酸盐脉石矿物与菱镁矿的分离问题。 菱镁矿选矿始于 第二次世界大战 前期，当时以手选为主。菱镁矿_百度百科

Curing performance of alkali-activated cement–phosphorous slag
Phosphorus slag (PS) is an industrial waste discharged during the refining of yellow phosphorus by a high-temperature electric furnace. The slag is generally deposited on the surface <i>in situ</i>, and this uses up considerable areas of land and causes environmental pollution problems. The glass phase content in electric furnace PS Publish Date: 25 April 2022. A new process of "gravity separation-flotation-acid leaching" purification was proposed for the removal of iron and titanium from a quartz sand in Sichuan. Fe and Ti were removed preliminarily from quartz sand by gravity separation and flotation, then purified by two-stage acid leaching.Study on a New Purification Process of Quartz Sand in Sichuan

Research Progress on Talc Inhibitors in Sulfide Ore Flotation
Many sulphide ore often coexist with magnesium silicate minerals such as talc. Due to its good floatability, talc causes difficulties in flotation separation of sulfide ore, affecting the comprehensive index of sulfide ore dressing. For such sulfide ore, it is often achieved by inhibiting talc. Flotation separation, so it is of great significance to study talc Based on the indoor HPG crystal water detection and uniaxial compression test and setting four different storage temperatures (20 ℃, 40 ℃, 60 ℃, and 80 ℃), this study explored the changes in the mass fraction of the crystal water of HPG samples under different storage temperatures.Effect of storage temperature on the cementitious property of
