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 ...

Silica IMA Europe

Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth’s crust. In spite of its simple chemical formula, SiO2 , silica exists in many different forms. Silica is found commonly in the crystalline state but occurs also in an amorphous state resulting from weathering or plankton fossilisation.

Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable ...

What is Silica? Eurosil

Since it is so abundant, quartz is present in nearly all mining operations. It is present in the host rock, in the ore being mined, as well as in the soil and surface materials above the bedrock, which are called the overburden. Most of the products sold for industrial use are termed silica sand. The word "sand" denotes a material whose grain size distribution falls within the range 0.06-2.00 ...

Silica / Glass Sand ArrMaz

Silica sand deposits are most often surface-mined in open pit operations but dredging and underground mining are also used. For industrial applications, deposits of silica yielding products of at least 95% quartz (SiO 2) are preferred. The production of such high purity sand requires that the extracted ore undergo significant processing to reduce impurities through the flotation of gangue ...
