Recently, several studies have shown the positive effect of sulfidization flotation on malachite surfaces and its enhancing methods. Therefore, this paper was focused ammonium sulfide sodium malachite, respectively; investigated using different devices such as micro-flotation tests, Zeta potential measurements, ToF–SIMS, XPS analysis, FTIR. Thus, Fourier transform infrared spectroscopy results ...

Coal mine drainage ochre is a ferruginous precipitate that forms from mine water in impacted watercourses and during treatment. With thousands of tonnes per annum of such ochre arising from mine water treatment in the UK alone, management of these wastes is a substantive issue. This paper demonstrates that the ochre from both active and passive treatment of coal mine drainage can be transformed...

Massive Zn-Cu-Fe sulfide deposits at the Garon Lake Mine occur in three sulfide lenses in a group of metamorphosed rhyolite crystal tuffs, metasediments and basalts. The major ore minerals are sphalerite, chalcopyrite, pyrrhotite and pyrite. Minor associated silicates are actinolite, tremolite, chlorite, albite and quartz. Rounded detrital pyrite, magnetite and chert grains and diagenetic p...

Abstract Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite affected many factors, causing it to easily enter concentrate and consequently reduce quality concentrate. Highly efficient depressants can be selectively adsorbed on surface improve its hydrophilicity, thereby increasing flotation separation efficiency. Understanding fundamental inhibiti...

Attachment of particles and droplets to bubbles—the latter being various fine sizes created by different techniques (as described in detail)—forms the basis flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays significant role this area, order for separation be effective, as stressed. This (brief) review particularly discusses wastewater ...

background: raw sewage contains various pathogenic organisms including bacteria, viruses, fungus, worms and protozoa. workers at wastewater treatment plants (wwtps) are exposed to these organisms as well as to h2s gas causing many health hazards. objectives: to assess some work-related health effects among wwtps workers with special emphasis on the most common infections as well as cardiopulmon...

The enrichment of polymetallic sulfide ore is a complex task. Fine grinding carried out to reveal useful minerals, resulting in the formation microparticles. It difficult achieve floatation microparticles and fine minerals are lost with flotation tailings. problem microparticle can be solved by using air bubbles smaller than 50 µmin for process. Water-air microemulsion (WAME)of frothersolution ...
