Let’s Talk: Silica in Open Cut Hard Rock Mining

What is the Concern about Silica in Hard Rock Mining? • The parent rock in most ore bodies contains some level of crystalline silica. The level in the ore body can vary widely depending on the geology of the area. • As part of the mining process, the rock is often blasted excavated, transported and crushed. During these processes the silica is broken down into very fine particles. These ...

Mining in the United Kingdom - Wikipedia

Brief history. The United Kingdom has a rich history of mining. Mining of non-ferrous minerals, particularly of copper and tin, has been ongoing since the Bronze Age. For example, copper was mined in Wales during approximately 2200–850 BC. Metalworking debris found beneath the ramparts at Beeston Castle in Cheshire is evidence of bronze production during the Bronze Age.
