The use of special apparatus for rapid analysis of ore production through γ-radiation

Abstract

RCS installations (radiometer, control, stationary) are widely used for operational determination of quantity and quality of dug ores and commercial yield in various conveyances, (carts, auto-trucks, boxes) and also for isolation of uranium rich broken raw ore, fill material, and dumped rock. This article gives the characteristics of these installations, describes the mine and geological conditions for their use and the problems that can be solved with their aid.

For purposes of rational adaptation of RCS-1 and RCS-2 installations to operational determination of excavation yield, evaluation of commercial yield, campaign against metal loss and impoverishment of ore, all mining enterprizes may be divided into two groups: 1) with gross extraction of ore; 2) with predominantly selective extraction of ore.

At mining enterprizes utilizing gross extraction, all the operational determination of produced and commercially useful ore is based on rapid γ-analysis of the entire cut stock in mine carts and trucks, by RCS-2 installations. When selective extraction is used, post excavation determination of ore yield is done with RCS-1 installations. This determination is the basis for yield testing of hydrothermal vein sources with low capacity but rich ore bodies. Rapid analysis of rich commercial ores also is done with installations of the RCS-1 type.

RCS-2 installations make it possible not only to determine operationally the activity in ore and rock in individual containers, but also to effect full automation of handling work for removal, sorting and unloading of mine carts with broken raw ore.
