Granite is one of the emerging industries of South Africa.Based on estimates South Africa has over 297 billion tons of granite reserves and more than 100 varieties of colours and verities of granite are available in South Africa. This study aims at providing ample details towards the prospective investors that would enable them in preparing realistic business strategy for the selected quarry.
Granite is included in the list of biggest minerals extracted amongst coal, chromites, rock salt, lime stone,china clay, dolomite, fire clay, gypsum, silica sand and so forth.Since mining&quarrying as consistently contributed 0.5 percent for the Gross Domestic Product. Production of Granite has grown substantially in the last twenty five years with total standing at about 5 million tons in 2003. It has been accompanied with high quarry wastage ranging from 61-73% in addition to poor quality, mainly due to unwieldy blasting techniques.
Granite processing basically involves sawing or cutting of raw blocks into the tiles/slabs of required size &thickness and polishing of sawn-off surfaces.Other ancillary functions involve edge cutting,milling, boring and contouring for enhancing thequality and price of production. In South Africa, the processing industry is in three sectors; namely,small-scale units, medium-scale units and 100% export-oriented units. The processing sector of granite inside the country has been developed over the years. The share in exports of processed material has increased.
This project is located in the Malay nicaea, mobile crushing mainly for the production of architectural sand aggregate screening system, the project by my company with Singapore T joint implementation process design, equipment manufacture, system installation and debugging, the system training delivery operation, this project because of considering the customer's periodic construction, at the same time in order to improve the efficiency of system installation, saving the cost of investment, the system is broken unit and screening unit adopts the tyre mobile solutions.Because the material source of the project is coarse aggregate produced by the original mine jaw broken by the customer, the project is designed with two-stage crushing and screening sections of medium and fine crushed cone, and equipped with vehicle-mounted container centralized control room.
Introduction to Dolomite
Dolomite crystal belongs to carbonate mineral of trigonal series, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, and is usually rhombohedral.Dolomite is mainly composed of calcium carbonate and magnesium carbonate. This stone appears to be very close to limestone in appearance. In fact, dolomite is often found in areas where limestone deposits are found.Dolomite can be widely used in building materials, ceramics, glass and refractories, chemical industry and agriculture, environmental protection, energy conservation and other fields.Moreover, the production of Dolomite ore in China is very large, which can not only meet the needs of relevant industrial production, but also has been exported abroad, and shows a good development trend.
