Definition of selective mining - Mindat

Definition of selective mining. i. A method of mining whereby ore of high value is mined in such a manner as to make the low-grade ore left in the mine incapable of future profitable extraction. In other words, the best ore is selected in order to make good mill returns, leaving the low-grade ore in the mine. Frequently called robbing a mine.

2021-3-26  Epigenetics is an essential biological frontier linking genetics to the environment, where DNA methylation is one of the most studied epigenetic events. In recent years, through the epigenome-wide association study (EWAS), researchers have identified thousands of phenotype-related methylation sites. However, the overlaps of identified phenotype-related DNA methylation sites between various ...

The horizontal drilling and selective solution mining method is ideal for Saskatchewan, as Saskatchewan is blessed with a wide-spread, flat lying, and well-defined prairie evaporite (potash) formation. Horizontal Well Pattern (Isometric of 3 caverns) Key benefits of selective dissolution.

Mining - Global Civil and Mining

2021-5-5  Mining materials with Surface Miners allows for a highly selective process, with individual layers or grades of the resource able to be extracted cleanly and in separate operations. This makes it possible to mine thin seams such as coal, or separate high- and low-grade pockets of ore that would otherwise be uneconomical or heavily diluted with ...

Mining Methods: Block Caving Geology for Investors

2017-3-15  Block (gravity) caving is a bulk underground mining method, which allows large low-grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted. It is a useful technique to extend the life of large deposits previously mined by ...

Cut and fill - QueensMineDesignWiki

2019-6-28  Cut and fill mining is a highly selective open-stope mining method considered ideal for steeply dipping high grade deposits found in weak host rock. Many variations of the general cut and fill technique exist, however this article will focus on overhand cut and fill.

Block caving - QueensMineDesignWiki

2019-6-28  Mining continues until all the ore has been removed. Selection Considerations. Caving is a non-selective, bulk mining method. It requires large-scale mineralisation in all three dimensions (length, width and height), in rock conditions that are sufficiently weak to allow caving and have suitably fine fragmentation, ...
