Graphite Mining. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.

Mining granite is a very large industrial process. The first step of making a granite slab is to mine the raw granite materials out of the crust of the earth in large, heavy blocks. Granite slabs are attained from specific sites that are known as quarries. Normally, miners choose quarries that are as close to the surface of the earth as possible.

Granite is usually formed into slabs or large deposits. There are different methods used by mining companies to cut and extract the deposits from the ground which are called quarries. When the granite is extracted, the mining team uses large equipment such as extractors and cranes to slowly dig around the deposits.

Mining crushed stone is more involved because the deposits are consolidated, meaning solid rock formations. The most common types of crushed stone come from deposits of limestone, dolomite and granite. To produce crushed stone, the massive formation first is drilled with a pattern of holes loaded with explosives by a licensed blaster.

The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons. (Such large blocks are subsequently divided into mill blocks weighing 15 to 70 tons.)

Granite Rock. Granite is the most common type of intrusive igneous rock in the Earth's crust. It forms when the molten rock or magma seeps in the gaps in sedimentary rock layers, and crystallizes slowly owing to its high silicate content. The entire process takes millions of years, and is just a small part of the rock cycle.
