Eurasian Resources Group (ERG) says it will be able to monitor moisture content and the chemical composition of the chromium ore extracted at its Kazchrome’s Donskoy Ore Mining and Processing Plant (Donskoy GOK) in a matter of seconds, on the conveyor belt, thanks to the installation of a GEOSCAN-M flow analysis system.
The new system, the first such system installed in Kazakhstan’s mining and metals industry, enables the real-time monitoring of moisture content and the concentration of five chemical elements (chromium, iron, calcium, silicon and aluminium) in ore, according to ERG. The margin of error does not exceed 1%. The analyser can process up to 1,200 t/h of ore at a conveyor belt speed of up to 2 m/s.
Traditionally, the chemical composition of the feed on the conveyor belt is monitored through chemical analysis of samples taken from the belt. The procedure takes several hours. ERG has decided to automate this process at Donskoy GOK as much as possible.
Late last year, ERG equipped the conveyor belt of crushing and processing plant No. 1 with the Bashnya Prob sampling system, eliminating the need for manual sample taking. With this system, the company’s specialists no longer have to move heavy samples, and there is no need to stop the belt line, so its throughput has increased. Now the GEOSCAN-M flow analysis system further streamlines the processing of raw materials.
Alexey Ganyushkin, Project Manager for the GEOSCAN-M chromium ore flow analysis system installation, stated: “The system is automated, and all the data is immediately sent to the information system of Donskoy GOK. Process engineers, miners and other specialists can monitor the chromium content in the ore in real time and adjust its processing accordingly. The system minimises technological errors and will help improve the accuracy of warehouse inventory control.”
