A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages,, the orehost rock association (, Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore.

 · In this index, you'll find pictures of minerals like those you'll most likely encounter in your expeditions. This list starts with the handful of common minerals called the rockforming minerals, followed by the most common accessory minerals—you'll find them stered in many different rocks but seldom in large amounts.

Finally, the typical ore bodies in Arizona were subjected to weathering at or near the surface of the Earth after eons of erosion removed overlying rocks. The weathering would remove much of the ore from the near surface rocks and leach them down to the groundwater interface where they would recrystallize as new minerals in an area called a supergene enrichment zone .

 · •A grid of tunnel is driven under the ore body, the rock mass then undercut by blasting. •Ideally the rock will break under its own weight, then ore is taken from draw points. Block caving is utilized to produce about 10% of underground metal .

Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical is also used in construction.

 · Silver is a precious metal loed throughout the world in geological deposits. Colorado's state nickname is the "Silver State" due to the large deposits of silver ore found there. Silver is extracted from the ore by a smelting or leaching procedure. Here's how to identify silver ore.

 · Silver ores, Silver Rocks and Minerals are easily fused before the blowpipe flame, either with or without carbonate of soda. The resulting globule of metal, of its characteristic white colour, can be readily hammered out or cut by a knife.

Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or siderite. Economically viable forms of ore contain between 25% and 60% iron.
