Sorption of Xanthate-type Collectors on Galena (1st Report)

Investigation of effect of sulfate ion on xanthate consumption in galena flotation based on thermodynamic diagrams

Flotation is a common process in sulfide ore beneficiation. Due to the restrictions and lack of access to high-quality water sources for industrial purposes, recycled water plays an important role in the flotation processes. Due to the existence of various organic and inorganic substances in the process, water influences the flotation performance. In this work, the effect of accumulation of sul...

Electrochemistry of Copper Activation of Sphalerite and Potassium Isobutyl Xanthate (KIBX) Synthesized Collectors Adsorption

Pancreas Transplantation and Report of 1st one in IRAN

SUMMARY Since 1923, the type I diabetic patients are treating with injections of insulin. Mortality of these patients decreased, comparing with noninsulin using patients, but many of them developed complications of diabetes mellitus, like nephropathy, retinopathy and neuropathy. The choice for treating this diseas and preventing its complications is pancrease transplantation, The 1st pancreas...

Selective separation of galena and sphalerite from pyrite-rich lead-zinc ores: A case study of the Kooshk mine, Central Iran

In this research, the selective flotation of galena and sphalerite minerals was evaluated from a pyrite-rich lead-zinc sample. An optimum mixture of selective collectors against pyrite and also organic/inorganic pyrite depressants was obtained in the flotation of galena and sphalerite by an experimental mixture design. The effect of different collectors and pH values were investigated in the ob...

Demonstration of Solar Heating and Cooling System using Sorption Integrated Solar Thermal Collectors

Producing cost-competitive small and medium-sized solar cooling systems is currently a significant challenge. Due to system complexity, extensive engineering, design and equipment costs; the installation costs of solar thermal cooling systems are prohibitively high. In efforts to overcome these limitations, a novel sorption heat pump module has been developed and directly integrated into a sola...
