How Do You Identify Silver Ore?

Silver ore is very rarely found isolated in individual nuggets of pure silver. It is much more common for silver ore to be found fused with other minerals such as sulfur, arsenic, antimony or chlorine. Because of this, it is helpful to quickly and efficiently test to see if a rock may have elements of silver ore trapped inside. This is done by heating the rock and submerging it in water. If

Silver stocks on the ASX: The Ultimate Guide

Silver, as well as zinc and lead, is extracted from the ore using grinding, sequential flotation and leaching techniques to produce high-grade lead and zinc concentrates with a high silver content. Cannington's is estimated to contain a total mineral resource of 55Mt at 184g/t silver from the underground sulphide and 30Mt at 98g/t silver from the open cut sulphide.

The History of Gold

Silver was used for small denomination purchases while gold was used for large denominations. The U.S. mint was legally required to buy and sell gold and silver at a rate of 15 parts silver to 1 part gold. As a result, the market rate for gold rarely varied beyond 15.5 to 1 or 16 to 1. That ratio would change after the Civil War. During the Civil War, the U.S. was unable to pay off all its

DIAMONDS Host Rocks

Diamonds are found in several rock types, but the primary commercial host rocks are kimberlite and lamproite [2]. And there are also secondary hosts known as placers that contain diamonds - like those found along the west coast of Africa. Diamond being extremely hard results in most gem-quality diamonds surviving transport in rivers, streams and even along coastal shores. Many coastal

High School Earth Science/Mining and Using Minerals

For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. Underground mines can be very deep. The deepest gold mine in South Africa is more than 3,700 meters deep (that is more than 2 miles)! There are various methods of underground mining. These methods are more expensive than surface mining because tunnels are made in the rock so that miners and equipment
