Abstract In this research, effects of chloride & sulfate ions and pH changes on the open circuit potentials of pyrite, pyrrhotite and steel and also their reduction–oxidation processes were studied. These potentials were measured at different pH values in 3 electrolytes: distilled water, sodium chloride solution and sodium sulfate solution. A pair of electrodes including reference and ...

Pyrite is one of the most common iron-bearing sulfides in nature, and it is a promising semiconductor with a band gap of 0.95 eV. Pyrite has been widely applied to the fields of photovoltaic cells, batteries, and valuable metal extraction [].Nevertheless, the oxidation process of pyrite generates acid mine drainage (AMD) and mobilization of As into the aqueous environment [].

The technique of modifying the surface properties of pyrite by oxidation in alkaline solutions, shown to be effective as a pyrite depressant during froth flotation, is also applicable to oil agglomeration (Wheelock, 1982). Coal fines are treated with an aerated solution of between 1 and 2% sodium carbonate at temperatures of between 50 and 80 ...

The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. This mineral's metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold because of its resemblance to gold. The color has also led to the nicknames brass, brazzle and Brazil, primarily used to refer to pyrite …

1.. IntroductionPyrite is one of the major diluents of copper, lead and zinc concentrates. One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc circuit to activate the flotation of sphalerite Bushell and Krauss, 1962, Voigt et al., 1994.

Pyrite recovery mechanisms in rougher flotation circuits. This circuit consists of four parallel banks of seven 130 m 3 mechanical cells. Results of testing the first rougher cell (approximately 69% Cu recovery), showed that 40–60% of pyrite in the finer class of the concentrate (−45 μm) was recovered by entrainment.

A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio.It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode.
