New enrichment technology is introduced at enrichment factory of KMAruda Works

The decision has been taken to introduce an additional stage of pulverization at plot No. 2 of the crushing and enrichment factory. Where before only two stages have been in effect—a first and second stage—now a third is being added that includes «Stack Sizer» screening machines produced by Derrick. The changes were made initially at the first technological section. Over the course of a month and a half, analysis was conducted of the performance of the three primary mills for the three secondary mills when the third stage of pulverization is applied. As a result, the iron content turned out to be higher. Thus, it has proven possible to achieve the appropriate quality indicators without reducing the load on the primary mills. A similar reconstruction is now underway at the second technological section. As a result, a universal technological schema with two sections will be achieved at plot No. 2 of the crushing and enrichment factory that will make it possible to process the maximum amount of ferruginous quartzites and achieve a high-quality concentrate.
