INFLUENCE OF AN ORGANIC POLYMER IN BALL-MILL GRINDING OF QUARTZ, DOLOMITE, AND COPPER ORE By A. R. Rule, 1 A. J. Fergus,2 and C. B. Daellenbach 3 ABSTRACT Research was done by the Bureau of Mines to determine the effect of a low-molecular-weight polymer on wet grinding of quartz, dolomite, and a copper ore.
Copper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process.
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 oxidised sulphide ore was studied by artificially oxidising a copper sulphide ore to various states during 16 months. For each oxidation state, the effect of chemistry was studied through a series of grinding and flotation tests completed under various grinding environments.
Copper ore with a particle size between 0–1 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the …
of the ore after comminution would cause significant impact on copper ore response in the floatation process. Comminution processes at the mine accounted for 49.8% of the total costs of production, i.e. 47% grinding to achieve a perfect liberation and 2.8% crushing costs meaning the overall results of the
comminution of copper ores from primary sources. Betwcen 40 to 60% of this energy is spent in fine grinding operations, typically togo from 85% below 6 mm to 40-60% below 200 Tylcr mcsh (74 !km). Available tcchnology is based on differcnt …

Wear rate of grinding media is variable function of ore components. • The largest share in the grinding media wear indicates sandstone ore. • Developed function describes relationship between ore lithology and grinding media consumption. • Results can be used to predict wear rate of grinding media during copper ores processing.
The present study initially investigates the kinetics of microwave-assisted grinding and flotation in a porphyry copper deposit. Kinetic tests were conducted on untreated and microwave-irradiated samples by varying the exposure time from 15 to 150 s. Optical microscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy were conducted to …
Grinding Copper Ores. Grinding in the process of copper ore grinding process of copper refining fine ore powder grinding process of copper refining fine ore powder Mill (grinding) A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting Such comminution is an important unit operation in many processes
to rising air bubbles in a water–ore pulp as the basis for separation [9]. There are many investigations on the electrochemical behaviors in grinding system and significance of grinding environment in mineral and ore flotation [8, 10-25] but these investigations are not reported for grinding of porphyry copper sulphide ores.
Copper ore grinding mill. Ball generator plays a huge role in the copper mineral ore grinding procedure. Zenith ball mill is definitely an efficient tool for milling walnut-sized copper ore in to powder. There's two ways of milling: the dry process and also the wet process.
