purification of copper by electrolysis metal extraction

Purification of Copper by Electrolysis (extraction from ore above) The impure copper from a smelter is cast into a block to form the positive anode. The cathode is made of previously purified copper. These are dipped into an electrolyte of copper(II) sulphate solution.

How Gold Is Refined: A Step

Even once the gold has been extracted from the earth, it's still in its raw form. It's still just raw ore that requires processing before it becomes pure gold. First, the ore is crushed. It then undergoes a series of processes that will vary depending on the different elements and minerals that are mixed in with the gold ore.

Properties of Metals Science Lesson

Sonorous: Metals often make a ringing sound when hit. Reactivity: Some metals will undergo a chemical change (reaction), by themselves or with other elements, and release energy. These metals are never found in a pure form, and are difficult to separate from the minerals they are found in. Potassium and sodium are the most reactive metals.

Gold Cyanidation

The resulting liquid is collected at the bottom, and the gold is chemically extracted. Heap leaching extracts less of the gold than processing the ore in a mill, but is much cheaper. There are a few alternatives to cyanide for processing low-quality ores but none are employed very widely to date (1).

Concentration of Ores: Hydraulic Washing, Froth Flotation

So nearly all rocks on the planet have some metal or mineral content. However, the concentration of this metal is too less for it to be valuable. Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of ores.

Difference Between Minerals and Metals

Metals have a shiny appearance and most of them have a silvery shine (except gold and copper). Since some metals are very reactive with the atmospheric gases like oxygen, they tend to get dull colors over time. This is mainly due to the formation of metal oxide layers. On the other hand, metals like gold and platinum are very stable and unreactive.

Copper Smelting

The precious metals present in the anode are not leached out during the electrolysis but remain in the form of a residue, which is referred to as the anode slime. Hydrometallurgical processes are then employed to refine this anode slime and obtain pure precious metals that are PGMs, Au, and Ag.

The Mining Process

Underground mines are used to extract minerals or metals from deep in the Earth. When building an underground mine, we dig a tunnel to get to the minerals. This can be a straight vertical tunnel called a shaft or a tunnel that spirals gradually downwards, called a decline. To access the ore from the shaft or decline, we dig other tunnels.
