Diamond: A gem mineral with properties for industrial use

Diamonds Used as an Abrasive. Because diamonds are very hard (ten on the Mohs scale), they are often used as an abrasive. Most industrial diamonds are used for that purpose. Small particles of diamond are embedded in saw blades, drill bits, and grinding wheels. These tools are then used for cutting, drilling, or grinding hard materials.

Opal Mining in Coober Pedy: History and Methods

The history of opal mining in Australia is one of danger, regeneration, and success against great odds. As far back as 4,000 BCE, humans have treasured opals and mined them in various locations, such as Kenya and Hungary. However, due to an unlikely combination of geology, fortuitous finds, and the two world wars, Australia has become the world's primary source of opal since the 1880s.

What are the main methods of mining?

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
