In this work, the parameters affecting the recovery of copper from the low-grade sulfide minerals of Sarcheshmeh Copper Mine were studied. A low-grade sulfide ore was used with a copper grade of 0.25%, which was about 28% of the mineral oxide, and the sulfide minerals made up the rest. Much more sulfide minerals were found to be pyrite and most of the gangue minerals were quartz, anorthite, bio...
The current paper introduces for the very first time recently invented electrodeposition-redox replacement (EDRR) method in continuous leaching-recovery-solution purification process. mini-pilot study reveals that longer duration of EDRR process is beneficial as it increases gold recovery per stage and decreases specific energy consumption EDRR. This extraordinary behavior postulated to be inhe...
Milling is among the most energy-consuming technological stages of copper ore processing. It performed in mills, which are machines high rotational masses. The start a mill filled to capacity requires appropriate solutions that mitigate overloading. One method for increasing energy efficiency ball mills optimize their drive systems. This article looks at two variants systems with efficiencies h...
This paper presents the new geochemical isotopes Sr and Nd, and the mineralization data for the south Neyshabour volcanic rocks located in NE Iran. Based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. All the analyzed volcanic rocks display enrichment in light rare earth elements (LREE) relative to th...
