BACKGROUND The aim of the present study was to determine the effects of feeding trace mineralsfortified mixed microbial culture (TMC) on ruminal fermentation, nutrient digestibility, blood electrolyte status, nitrogen balance, and trace mineral balance in sheep. METHODS Mixed microbes [0.6 % (v/w) of Enterobacter sp., Bacillus sp., Lactobacillus sp., and Saccharomyces sp.] were cultured with ...

The Wushan Operation has been studied as a case study, particularly relevant to the copper-molybdenum separation circuit, in which efforts have made improve quality of molybdenum concentrate through diagnostic analysis. A key finding appearance coarser silicate minerals due their inadvertent activation flotation. suitable flotation conditions occurs, most likely, upstream bulk regarding usage n...

Monitoring of the microbial community in bioleaching processes is essential in order to control process parameters and enhance the leaching efficiency. Suitable methods are, however, limited as they are usually not adapted to bioleaching samples and often no taxon-specific assays are available in the literature for these types of consortia. Therefore, our study focused on the development of nov...

Reuse of process water in the flotation sulfide ores has crucial importance for environmental sustainability and improved economy. However, chemistry may be a critical subject efficiency as dissolved ion concentration increases with reuse. In this study, effects reuse on Cu-Zn ore were investigated. The flowsheet consists pre-flotation section to remove naturally floatable talc particles, seque...

The efficiency of grinding and flotation process in copper-molybdenum processing circuit, largely affected by performance thickeners hydrocyclones devices. goal this paper is to investigate the effect rate-limiting factors on these devices consequently separation molybdenum circuit. So, a full mineralogical study have been carried out outputs hydrocyclone molybdenite According results, coarse-g...

The study of the depression effect non-toxic depressants on flotation separation chalcopyrite from galena is great importance for both industrial applications and theoretical research. mixed depressant (DFinal) four common inhibitors—sodium carboxymethyl cellulose, sodium silicate, sulfite, zinc sulfate—exhibited high selectivity during galena. Flotation tests an copper–lead bulk concentrate sh...

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...
