What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ 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.

Types of Mining Methods Sell Side Handbook

Mar 10, 2018· Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate (since some ore is left behind in pillars). Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom. Direct operating costs for room-and-pillar

A hybrid decision tree/genetic algorithm method for data

Jun 14, 2004· Ting proposed the use of a hybrid data mining method to cope with small disjuncts. His method consists of using a decision-tree algorithm to cope with large disjuncts and an instance-based learning (IBL) algorithm to cope with small disjuncts. The basic idea of this hybrid method is that IBL algorithms have a specificity bias, which should be

Magnetic and Gravity Methods in Mineral Exploration: the

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
