the need to separate ore from other rock

How to separate iron ore from rock. But the ore's journey to becoming a usable metal is only just beginning when the ore leaves the mine. Mining produces a mixture of rocks that contain ore and other rocks that do not contain ore. So, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore.

Extracting Gold HowStuffWorks

2009-02-23  To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Separating Metals from Mud - Mining Technologies ...

2011-03-27  The ore which we dig out of the ground is a combination of rock and the useful minerals we want. The problem is the proportion of the useful minerals can be only 1 or 2 percent, and that's still worth extracting. And this process of extracting the valuable minerals out of the rock is incredibly difficult.

The rock is then crushed by powerful machinery. Metal is extracted from the crushed ore by one of two major methods: smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore. Smelting usually requires a reduction agent, or another chemical, to separate metal from its ore.

Rock Crushing methods and How to recover gold from Ores

It just takes a lot of elbow grease and work to break up the rock. A slightly different version of mortar and pestle work is a variety called hand stamp crushing. A heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder. This iron cylinder is picked up and dropped onto the ore, much in the manner of

metallurgy: Separation of the Metal Infoplease

If the ore is an oxide, it is heated with a reducing agent, such as carbon in the form of coke or coal; the oxygen of the ore combines with the carbon and is removed in carbon dioxide, a gas (see oxidation and reduction). The waste material in the ore is called gangue; it is removed by means of a substance called a flux which, when heated, combines with it to form a molten

extraction of metals - introduction

The ore is first crushed and then treated with something which will bind to the particles of the metal compound that you want and make those particles hydrophobic. "Hydrophobic" literally means "water fearing". In concentrating copper ores, for example, pine oil is often used. The pine oil binds to the copper compounds, but not to the unwanted rocky material. The treated ore is
