Redox Reactions. Think of the reaction between zinc and copper. Instead of placing a piece of zinc directly into a solution containing copper, we can form a cell where solid pieces of zinc and copper are placed in two different solutions such as sodium nitrate. The two solids are called electrodes.

Zinc might re generate thiosulfate concentration and precipitate most of copper in the solution. Aluminium precipitation might recover gold with less amount of copper deposition and some thiosulfate reduction. Copper precipitation reduced a small amount of thiosulfate concentration and greatly increased copper concentration. Ammonia concentration

Monel metal is a so called natural alloy prepared by the reduction of a copper nickel ore; it contains 65 to 70 percent nickel, iron and manganese in small amounts, and certain impurities that influence its properties to some extent. It has been widely used for various engineering and ornamental purposes and possesses exceptionally high strength at both normal and elevated temperatures.

Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Since each mine site is unique in its mineral composition, concentration, and quantities, the most economical and profitable processing of ore must be determined by the mine planners. When it is economically feasible, a mine may extract both types of copper minerals; when it is not possible, mines will only process either the copper oxides or the copper sulfides. The first steps of copper processing are the same for both ores

Oxidation Reduction Reactions Redox   Shodor

Oxidation Reduction Reactions Redox Shodor

Like acid base reactions, redox reactions are a matched set you don't have an oxidation reaction without a reduction reaction happening at the same time. Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons. Each reaction by itself is called a "half reaction", simply because we need two (2) half

the effect of changing conditions in enzyme catalysis

The effect of substrate concentration on the rate of enzyme controlled reactions. If you know about orders of reaction, the reaction has now become zero order with respect to the substrate. In the same way that every enzyme has an optimum temperature, so each enzyme also has an optimum pH at which it works best.
