Earth Structure, Materials, Systems, and Cycles Objectives Since this course is about how Earth processes can adversely affect us as human beings, we need to first discuss some of the basic principles of the science of Earth that is geology.
Mineralogical information is an essential component of drainage chemistry prediction because mineralogical properties determine the physical and geochemical stability and reaction rates of geologic materials and mine wastes. This section provides an overview
Developed by a German mineralogist, Friedrich Mohs, the Mohs Hardness Scale assigns hardness values to 10 representative minerals as well as other common materials (penny, knife blade, etc.). Talc is the softest mineral and diamond is the hardest mineral.
coarse material deposits on top of fine grained marine sediments (ex. ash from Mt. Manama on top of sediment = important time marker in PNW sediment) liquefaction loss of cohesion in water saturated material due to shaking = landslides etc.
level of water in the mine is 70 feet below the 700 foot level. If the mine is depleted as a source of water, Socorro Mining has permission to take water from the Central Arizona Project canal. The application fee is $500.00 with a $100.00 charge for the first 5 acre/feet used.

Gilsonite companies have used other mining equipment in the past including, bulldozers, a small tunnel boring machine, and water jet cutters mounted on mine cars and surface drill rig bits. The American Gilsonite Company is currently testing a compressedair powered, continuous mining machine with a rotary mechanical cutting head.

Underground mining is used for ores that are deep in Earth's surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. Underground mines can be very deep. The deepest gold mine in South Africa is more than 3,700 meters deep (that is more than 2 miles) There are various methods of underground mining.
The reflectance data were then mapped using the USGS Tricorder algorithm (Clark et al, 1990, 1991, 1993a, 1995, 1998) testing for the presence of 253 materials. These materials included mineral, mineral mixtures, water, vegetation, environmental pollutants, and other materials.
Open pit mining The process of mining an ore body from the surface in progressively deeper steps. Sufficient waste rock adjacent to the ore body is removed to maintain mining access and to maintain the stability of the resulting pit. Open pit A mine that is entirely on surface.
Processing of ore from a lode mine, whether it is a surface or subsurface mine, requires that the rock ore be crushed and pulverized before extraction of the valuable minerals begins. After lode ore is crushed, recovery of the valuable minerals is done by one, or a combination of several, mechanical and
The portability of the TerraSpec Halo allows the Mine Geologist to field identify valuable and problematic mineralogy in ores for stockpiling, extraction, and other tasks. This efficient ore control method reduces risk and provides the finest ores for processing, which reduces costs and increases profits.
For example, the sample may be an ore sample obtained during the development of a new mine or during ongoing extraction of material from an existing mine. In some mines for example, deposits are spatially variable and ongoing analysis is important for ore sorting or for ore processing optimization.
Substantially greater contrasts in the degree of resistance are used to identify and locate boundaries among different materials as well as the presence of cavities. This technique helps mining companies improve accuracy and reduce time and costs before mine development commences.
Beyond the geologic map, valuable geologic data may be available in state geologic survey reports, scientific journals and federal geological survey assessments. Fortunately, Internet searches can quickly identify such resources.

Mine tailings are composed of the waste minerals removed from the ground in the mining process. As these minerals are exposed to the atmosphere and to rain water, they can react to form new
These more difficult mining situations will have an effect on economic decisions related to mine profitability, on the health and safety of mine workers as they encounter more challenging or different mining requirements, on the technical ability to mine, and on the management of waste materials generated by mining.
