7. First used for drilling oil wells in 1860's. Cheap and reliable way to drill water wells. It is a drilling technique in which a sharpened steel bit attached to rope or cable is repeatedly raised and lowered at the rate of 30-60 strokes/min and crushing the rock and making the hole deeper. The crushed rock and sludges are removed by a bailer to the bottom of the …

Gold is also present in our oceans in trace quantities. The actual concentration is in the order of 20 μg of gold per liter of seawater, which, considering there are over 1x1021 L of seawater, means that the oceans contain over 20 million tonnes of gold. At a typical gold price of around US$300 per troy ounce (31 g) this makes the sea worth US ...

This document provides an overview of the mining process from exploration to extraction and processing to reclamation. It explains that exploration uses tools like satellites, planes and helicopters to identify mineral deposits, and involves geological mapping and sampling. Once an area looks promising, drilling extracts core samples for analysis.
