Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds. Even after extraction, the rough diamond is still far from being set in an engagement ring.

Extraction of Metals Good Science. Carbon reduction of metals metals with an intermediate reactivity, such as iron and zinc, which form part of minerals, need to be chemically extracted from ore this is done by a process called carbon reduction carbon reduction is a type of displacement redox reaction, where carbon is used to displace the metal from the mineral compound the crushed ore is ...
The primary methods used to extract minerals from the ground are Underground miningSurface open pit miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

The process for extracting salt from sea water is an ancient technology and involves evaporation ponds. Shallow, water-proof ponds are dug out and connected to the sea by means of a short canal. A broad area and shallow depth allow a given volume of water to absorb more sunlight. The pond is flooded, and then the canal is closed.

Minerals are naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color and hardness. For example, copper pyrite CuFeS 2, calamine ZnCO 3 etc. are minerals. A mineral from which metal can be economically extracted in a maximum amount is called an ore.

These two lessons use the minerals from the relatively inexpensive 10 Toysmith Mineral Science Kit.
Copper Mining and Extraction Oxide Ores. The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining
Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
SaltHalite Mining Process. Salt is generally produced one of three ways deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.
