Mining Sequence
Mining refers to the process of extracting valuable minerals or other geological materials from the earth. The mining process of extracting mineral resources comes with a variety of environmental and technological considerations. Different resources are evaluated in order to access their potential profit, environmental effects, and the cost of extraction and refining of the material. The most effective sequence of operations to extract mineral resources is critical in ensuring success of any such operation.
The most common and successful sequence of operations in mining are as follows:
1. Preliminary Exploration: An effective preliminary exploration is essential in finding a mineral deposit which is likely to be profitable. Through the process of reconnaissance and aerial surveys, geologic maps and different geophysical techniques are used to effectively identify the location and concentration of the deposit that is to be mined.
2. Geological Mapping: Geological mapping is an essential part of the mining process. Through the creation of a geological map, the prospectors can determine the thickness, grade and limits of the ore body as well as the associated mapping of the ground surface.
3. Geological Sampling: Geological sampling is the next step in the mining process. This is used to estimate the grade and quality of the mineral resource. Sampling includes surface sampling procedures at the surface and underground sampling operations.
4. Drilling Operations: Drilling operations are the next step in exploring and evaluating a mineral deposit before mining. Drilling is used to determine the limits, grade, thickness and continuity of the mineral.
5. Mining Plans: Mining plans help identify the mining method to be used, the area to be mined, the equipment to be used, as well as safety measures required.
6. Mining Operations: Mining operations are an essential part of the mining process. The mining methodology used is dependent on the characteristics of the mineral deposit and the size of the operation. Some common mining methods include underground mining, open pit mining, contour mining, dredging and highwall mining.
7. Ore Processing: Ore processing follows mining operations, wherein different ore grades are sorted prior to further refining.
8. Site Reclamation: After mining is complete and all the ore has been extracted, the mining site requires reclamation procedures. This can include waste management, soil treatment, removal of remaining structures, as well as monitoring and maintenance of the area.
Mining has been an important industry for centuries and has come with a variety of considerations and regulations. By following the effective sequence of operations listed above, miners can ensure they have a successful and profitable mining site while successfully considering the safety and environmental impacts.
