Ore is a deposit in Earth's crust of one or more valuable most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. It is a common material in pipes and plumbing material.

8. Check the mining pan periodically to see if the gold is extracted. Pull the mining pan out of the water and look at the pieces that remain in the pan. Pick out any gold pieces and place them in a separate container. Continue to shake the mining pan in the water until you've picked out all of the gold pieces.

Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.

Iron ore was won by drilling and blasting (Fig. ).As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be selfsupporting. However, he states that in later years where the mining had progressed to the ...

Leaching/Extraction of Gold from Ore. Leaching is a gold extraction process that aims at producing a gold solution as an intermediate product by dissolving out the gold from a goldbearing ore using an appropriate reagent (see Fig. ). In current industrial practice, leaching is effected using an alkaline cyanide solution.
