Correct, modern geochemical techniques for gold often target gold at extremely low levels, generally at parts-per-billion (ppb) and even down to parts-per-trillion (ppt) in waters and specifically targeted resistate minerals. Portable XRF has a lower limit of detection (LOD) in the order of 2–5 parts-per-million (ppm) and thus not sensitive ...

One popular approach for ore analysis in mining is the use of X-Ray fluorescence (XRF). In XRF, the sample of interest is irradiated with high-energy electromagnetic radiation, and the emitted photons are detected. Using high-energy X-Rays causes the ejection or promotion of core electrons, rendering the element energetically …

Surface coal mining poses a particular set of geotechnical challenges to decommissioning engineers. These include the long-term stability of the slopes around the edges of the pit, particularly when the pit is likely to gradually fill up with water in the years after the mine has stopped functioning. Investigating slope stability issues such as ...

Feb 12 2014. The latest article in our series reviewing the fundamentals of mining looks at the method of block caving. Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization.
Mining asteroids is a big leap from sample collection missions to mining resources from asteroids, but some commercial entities are already making the first tentative steps to reach this goal. Cost-effectiveness is at the forefront of these operations. Asterank⁴ is a scientific and economic database of more than 600,000 asteroids.

The removal of the ore causes a large gap or 'cave' where the orebody previously resided. Specific examples of cave mining techniques include block caving, panel caving, inclined-drawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, room-and-pillar mining and front caving. Cave mining is typically used to mine ...
