The article describes the effect of fluxing ability (FA) ores used as a flux on slag formation and copper losses. In Kazakhstan, at Balkhash smelting plant (BCSP), currently fluxes have very low SiO2 content—about 62%—whereas Al2O3 content is 12%. Its was estimated, it shown that silica an exceedingly FA. Only half participate in formation. To obtain slags with magnetite concentration, consider...

bioleaching processes for extraction of cu and mo from molybdenite cons. are more environmentally friendly and consume less energy than conventional technologies, yet less economically efficient. one necessary step towards arriving at a cost-effective bioleaching process is using appropriate methodology to optimize pertinent factors in such processes. to this end, the present study employed res...

Prevalence of anthelmintic resistance in gastrointestinal nematodes (GIN) of goats has necessitated studies for alternative means of control. The objective was to determine the effectiveness of dietary copper sulfate for control of GIN in meat goats. Naturally infected buck kids received 0 (LC), 78 (MC) or 158 (HC) mg copper sulfate (CS)/kid daily mixed with concentrate supplement for 63 days. ...

Redox potential (Eh) control plays a significant role during sulfide mineral flotation by influencing the reactions on surface of minerals and accordingly behaviour. In this study, metallurgical performance typical copper minerals, molybdenite as well gangue (e.g., pyrite, tennantite, enargite) under different pH Eh conditions cell were investigated. The molybdenum processing plant at Sungun co...

Copper mining is one of the largest economic activities in Zambia, comprising close to ten percent of GDP. Between 2003 and 2008, the price of copper increased by over 400 percent. In response, copper production in Zambia increased by 70 percent and employment in copper mining increased by nearly 200 percent. This paper examines the effect of this economic shock on sexual behavior and the sprea...

Abstract The demand for copper is expected to outpace supply in the coming decades due part emergence of wind and solar technologies, which require about five times as much traditional energy sources. This work introduces a potentially transformative hydrometallurgical process extract from chalcopyrite, thereby sustain high rate production throughout 21 st century. Chalcopyrite reacted with van...

To study the effect of feed additive N- carbamylglutamate (NCG) with different levels feeding on amino acids profile and some analytes in serum goats, thirty male goats aged 7-8 months were distributed into three concentrate 2%, 3%, 4% or without NCG a 2×3 factorial experiment/ Completely Randomized Design (CRD). After 72 days individual feeding, blood from jugular vein was obtained before morn...

Chalcopyrite is the resource with highest amount of Cu content representing around 70–80% known reserves in world. However, chalcopyrite like other copper sulfides, usually found deposits grades 0.4–0.5% copper. The exploitation these using traditional flotation methods followed by pyrometallurgical treatment concentrate at limit economic viability. Hydrometallurgical route would be more suitab...
