- W3137048468 abstract "Konkola West Concentrator stockpile handles 55000 tonnes copper ore per day producing an average of 400 tonnes of concentrate. The grade of the concentrate is 36 to 40% TCu. The plant efficiency (recovery) is at 89% TCu. The concentrator operations include: Primary, secondary and tertiary crushing, grinding, flotation, dewatering and tailings disposal. The objective of this study was to investigate optimum grind of a blended copper ore comprising sulphide and oxide minerals with a view to achieving an optimal flotation performance in the treatment of the Konkola Copper Mines ore in Chilabombwe. This required an in-depth analysis of the mineralogy of the feed as well as tailings samples after different flotation processes involving a range of reagent types and dosage procedures. The in-depth analysis included the analysis of the percent Total Copper (%TCu) and percent Acid Soluble Copper (%ASCu) of the feed, concentrate recovered and the tails. The reagents used in the flotation process included; Sodium Isopropyl Xanthate (SIPX), Frother Zambia Konkola (FZK 245) and Sodium hydro-Sulphide (NaHS). The ore samples studied represented a high quality (HQ) ore dominated by sulphide minerals and low quality (LQ) ore dominated by oxide minerals. The project was initiated on the 18th of August, 2015. The experimental results showed that optimization of grind for the blended copper at different grinding times was successfully achieved and can be used to increase the concentration of copper at KCM West concentrator." @default.
