A Brief Introduction to the Types of Surface Mining Methods

Dredging is a method of obtaining mineral deposits from the bottom of rivers, oceans, harbors, and streams. As compared to other mining methods, where the ore has to be accessed by removing material above it, in this case, the river makes the job easier by directly transporting minerals from

Factors Affecting Exploitation of Mineral Resources around

The method of mining depends on the mode of occur­rence of the ores. The open-cast mining is the cheapest, while shaft mines are very expensive. The cost of mining also depends on the scale of operations. If the mining has been done at a large scale, the capital and running costs can be offset.

Brief History of Mining & Advancement of Mining Technology

In today’s technologically-advanced society, mining techniques are always improving. For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers.

Efforts to solve the various problems, which have required intensive research, have delved into

3 Technologies in Exploration, Mining, and Processing

The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of mineral concentrates or refining of metals.

Suitability of the overhand cut-and-fill mining method for

Abstract: Vein type carbon-rich graphite deposits found in Sri Lanka occur in metamorphic rocks as narrow steeply dipping veins. These graphite deposits are mined by underground mining, mostly by applying the overhand cutandfill method. Graphite mining at Bogala mines, Sri Lanka, is a unique example of narrow vein mining where the overhand cut-and-fill method is applied as the most
