Calcite Quarry, Michigan

Calcite Quarry ships between 7 and 10.5 million tons of material each year, thanks to the quarry’s location on the shores of Lake Huron. Nearby Rogers City was once a typical mining company town, but over time it has expanded its economic base as a summer retreat for sailing and tourism.

Michigan Limestone and Chemical Company - Wikipedia

Michigan Limestone and Chemical Company (a.k.a. "Michigan Limestone") operates the world's largest limestone quarry located near Rogers City, Michigan. It was founded in 1910; however, production didn't begin until 1912. Ownership of the quarry has changed a number of times in recent years, but it is still one of the country's largest producers of limestone.

Mining Magic — Made In Utah

Oct 09, 2018  Back in 1995, valuable calcite deposits were discovered in Northern Utah and Shamrock Mining Associates would gain the exclusive mining rights to Utah’s beautiful Amber Onyx, also called Honey Onyx or Honeycomb Calcite. The “explorer” who made the discovery was Floyd Anderson, now a vibrant 95-years-old.

Galena - Wikipedia

Galena is the main ore of lead, used since ancient times.Because of its somewhat low melting point, it was easy to liberate by smelting.It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.In these deposits significant amounts of silver occur as included silver sulfide ...

Garnet mining in New York State dates back to the late 19 th century when the Barton Mine first opened in 1879. Henry Barton experimented with garnet as a harder and more durable abrasive than simple sand and after a fisherman friend told him about the prolific garnets in the Adirondacks he staked his claims and went into production (Kelsey, 2015).

Low Sulphidation Epithermal Gold Deposits

Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling – caused by a drop in the confining pressures the fluid approaches the surface.
