Newsletter
During mineral sample preparation, geological material is brokendown into a fine, dry pulp that can be subsampled to provide a representative sample of the original rock. Sample preparation is key in ensuring that the target elements are effectively released from the rock for decomposition and further analysis. Quality protocols are followed at AGAT Laboratories during all stages of sample ...

Earth Science for Kids: Rocks, Rock Cycle, and Formation
For example, shale, a sedimentary rock, can be changed, or metamorphosed, into a metamorphic rock such as slate or gneiss. Other examples of metamorphic rocks include marble, anthracite, soapstone, and schist. Igneous Rocks Igneous rocks are formed by volcanoes. When a volcano erupts, it spews out hot molten rock called magma or lava. Eventually the .

Drilling Techniques for Mining Exploration
· A "core" of rock is left in the center of the pipe, which is then recovered as a sample. This core can then be analyzed to determine more about its composition as well as the relationship between rock layers. A high rpm of 300 to 1200 is required for diamond core drilling, with weight and penetration constant to ensure that the core is not washed away. Performing diamond core drilling ...
