metamorphic schist mining equipment

Major Mines & Projects

After mining the shallow ore from Buffalo, the mining fleet will move to Elephant to mine the shallow ore in year 5. Over the first 7 years of production the strip ratio will be extremely low, approximately 0.2 (waste to ore ratio), and the mining rate will be approximately 1.7Mtpa (including ore and waste).

Staurolite schist (3.8 cm across). Staurolite schist has prominent dark brown staurolite crystals in a light-colored muscovite schist matrix. It is an intermediate- to high-grade metamorphic rock. The mineral staurolite (Fe,Mg,Zn) 2 Al 9 (Si,Al) 4 O 22 (OH) 2 - iron magnesium zinc hydroxy-aluminosilicate) often forms cruciform twins - two intergrown crystals forming a cross or X-shaped form.

Utica Mine (MRDS #10310689) AU

Large bodies of mineralized schist also form low-grade ore bodies throughout the Mother Lode. This ore consists of amphibolite schist that has been subjected to the same processes of alteration, replacement, and deposition that formed the greenstone gray ores. The altered schist consists mainly of ankerite, sericite, chlorite, quartz, and albite.

Pine Tree-Josephine Mine (MRDS #10310715) AU

In the Josephine mine, both the Pine Tree and Josephine veins were explored to depths of 700-800 feet, but nearly all the mining took place within the upper 300-400 feet. High gold grades in both veins, within a hundred feet of the surface, were 1.2-2.5 ounces per ton (opt) gold, and may have been due to secondary enrichment.

What Are Metamorphic Rocks? - Mining Fundamentals. Metamorphic rocks are formed at a depth of 12 to 16 km beneath the Earth''s surface, where high temperature, pressure and chemical alterations cause transformation of pre-existing rocks into another type of rock. They are formed through a process called metamorphism.

Geology | Bisbee mining and minerals

Pinal schist . This unit is the basement for much of southern Arizona and, at Bisbee, is of an unknown thickness. It has been dated at 1.7 billion years old. Essentially, it is a fine grained, fissile, quartz-sericite schist that was most probably the result of regional metamorphism of thin-bedded, clastic sediments (Bryant & Metz, 1966).
