Gold Mining Mining Shares

A lower grade gold ore would contain something like 5 grams per tonne (5 parts per million). So gold ore needs to be concentrated by about 1,000 times above its average dispersion to become viable for gold mining. The process of gold concentration happens both above and below the surface of the Earth.

The Basics of Successful Gold Mining

Most successful river miners use the following technique to locate and recover pay-streaks: First, locate a proven gold producing section of the river. By digging or dredging sample holes, locate the main gold path. More sample holes are continued along the path until a pay-streak is located.

Mine For Gold

Another benefit of modern gold mining equipment is the recovery rate. Early stamper batteries set up to crush gold out of quartz reefs were recovering only 45% of the gold and silver from the raw ore. In 1889 the New Zealand Crown Mines Company at Karangahake was the first company in the world to trial cyanide in gold recovery.

9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
