Test Research and Application of X-ray Intelligent Separation in Xitieshan Lead-zinc Mine
In order to determine the economic and reasonable discarding rate of Xitieshan Lead-zinc Mine,the X-ray intelligent separation test was carried out for the raw ore.The test results show that it is technically feasible to use X-ray pre-separation in Xitieshan Lead-zinc Mine.When the particle size of the raw ore is 10~65 mm,the separation effect is the best.When the discarding rate is 41.91%,the grade of lead and zinc in the pre-selected tailings is within 0.10%,and the sulfur grade is 0.63%.The recovery rates of lead,zinc and sulfur concentrate are 99.23%,99.09%and 97.54%,respectively.On the basis of the experimental study,the X-ray pre-discarding technical transformation of semi-autogenous mill refrac-tory stone was carried out on site.The discarding rate of refractory stone is more than 40%,the grade of lead + zinc in waste stone is less than 0.25%,and the production indexes of mineral processing plant are improved.
