Iodometry,  · Iodometry, known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point. Note that iodometry involves indirect titration of iodine liberated by reaction ...Froth flotation,  · Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the ...3 Ways to Make Copper Sulphate in a Science Lab,  · To make copper sulfate in a science lab, start by pouring sulfuric acid into a glass beaker and heating it until it's almost boiling. Then, carefully add small pieces of copper oxide to the hot solution, stirring the mixture lightly for 30 seconds after each addition.RISE project,  · The RISE Project (Rivera Submersible Experiments) was a 1979 international marine research project which mapped and investigated seafloor spreading in the Pacific Ocean, at the crest of the East Pacific Rise (EPR) at 21 north latitude. Using a deep sea submersible to search for hydrothermal activity at depths around 2600 meters, the project discovered a series of vents emitting dark mineral ...Recovery of pyrite from copper tailings by flotation,  · Copper tailings contain reactive sulfide minerals, such as pyrite, chalcopyrite, chalcocite, and other residual metal minerals . Sulfide minerals, mainly pyrite, in the presence of air, water, and bacteria can suffer a rapid oxidation to produce acidic water ..

Learn About the Common Steel Alloying Agents,  · Copper (0.1-0.4%): Most often found as a residual agent in steels, copper is also added to produce precipitation hardening properties and increase corrosion resistance. Lead: Although virtually insoluble in liquid or solid steel, lead is sometimes added to carbon steels via mechanical dispersion during pouring in order to improve machinability.
