Mining Geography Form 1 Notes. Method of Mining. A mineral requiring open cast mining will be mined even if the mineral deposit is large but one requiring underground mining will be extracted if its in large deposit or if its of high value or rare. Transport costs.

This practical stepbystep guide describes the key geological field techniques needed by today''s exploration geologists involved in the search for metallic deposits. The techniques described are fundamental to the collection, storage and presentation of geological data and their use to locate ore.
#0183;#32;In practice, however, the application of any data mining method should be carried out following the above process to ensure meaningful and useful findings. In this paper, spatial data mining and geographic knowledge discovery are used interchangeably, both referring to the overall knowledge discovery process. 2.
Mining Mining Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
GEOGRAPHY FORM TWO: Topic 5: SUSTAINABLE MINING Faragha Nasson. The methods involved in the mining process are placer method for alluvial diamond and shaft method for the diamond found in the deep ground. Diamond is used for making jewels, manufacturing the drilling bits, making cutting instruments like for cutting glass,

MINING. Mining has a long history in Africa. In North Africa, people have mined for iron ores and other metals for more than 2,000 years. Iron mining began in subSaran Africa by around 500 and had spread through the region by the 200s. Iron played a crucial role in the improvement of agricultural tools and weapons.
Mining Methods Development of Mining Methods. The first method of mining coal from Kansas rocks was a primitive form of stripmining which may be aptly termed quot;cropworking.quot; Possibly the Indians were the first to employ this method of removing coal from the outcrop by means of crude hand implements.

Mineral and Power Resources. Minerals: A naturally occurring substance which has a definite chemical composition is called mineral. Minerals can be identified on the basis of their physical properties and chemical properties. Ore: A rock from which a particular mineral can be profitably extracted is called ore. Out of more than 28,000 types of minerals known till date, only about 100 are
Prospecting, search for economically exploitable mineral deposits. Until the 20th century prospecting involved roaming likely areas on foot looking for direct indications of ore mineralization in outcrops, sediments, and soils. Colours have been a traditional guide to ores. The reds, browns, and
