石棉选矿就是将石棉纤维和蛇纹石分开,并且要尽量保持石棉纤维原来长度,减少它的损失,以便得到较多的长纤维石棉.但是由于石棉的比重与蛇纹石差不多,所以选矿一般多利用石棉纤维块和蛇纹石(废石)的磨擦系数不同来进行选矿.石棉纤维的磨擦系数是0.7到0.9,而纤维蛇纹石是0.3～0.5.这个方法是在石棉纤维未松解开的情况下采用,也在选长纤维石棉时使用. 另外由于同样体积、密度的岩石和纤维,在水中或在空气中,纤维的运动阻力比岩石大得多,所以它比岩石落下缓慢一些.矿石中夹
Asbestos beneficiation separates asbestos fiber from serpentine, and tries to maintain the original length of asbestos fiber and reduce its loss, so as to obtain more long-fiber asbestos. However, due to the similar proportion of asbestos and serpentine, the beneficiation is generally much. The use of asbestos fiber block and serpentine (waste rock) of different friction coefficient for beneficiation. Asbestos fiber friction coefficient is 0.7 to 0.9, and fiber serpentine is 0.3 to 0.5. This method is not loose in the asbestos fiber It is also used in the case of long fiber asbestos. In addition, due to the same volume and density of rock and fiber, the resistance to movement of the fiber in water or in air is much greater than that of rock, so it is slower than rock. Ore folder
