Mineral

are hosted by reduced-facies marine or lacustrine rocks such as green, black, or gray shale, siltstone, thinly-laminated tidal facies or reefoid carbonate rocks, and dolomitic shale. The deposits consist of stratabound, disseminated copper sulfide minerals that occur in reduced-facies sedimentary rocks, which overlie, or are interbedded with, red-bed sedimentary sequences or subaerial basalt flows. Copper is mobilized in the red beds by oxidized brines and is derived from reduction of sulfate in…

If you've seen the late night infomercials or the shopping channel shows proclaiming the benefits of mineral makeup you are probably wondering if this is all too good to be true or if these products might be a great solution for you. It is important to remember that there are no solutions that are right for everyone and that there are many, very different mineral makeup companies out there. You will really need to try more than one before you make the decision that this is definitely not for you…

Initially, the most striking feature of Eroded Rock, Point Lobos, a gelatin silver print by Edward Weston, is its relationship between positive and negative space. The photo’s subject is an eroded rock, whose rough, raised plateaus create a light positive space and emerge from smooth, blackened sections of the eroded rock which create the image’s negative space. These sections of eroded rock envelop the plateaus in languid serpentine lines, almost as though the plateaus are land masses cast…

1. Observation. - Compound X is a white powder. It is a solid. 2. Questions. - What is compound X? - What will happen when compound X is heated and reacted with C20H14O4 (phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with…

These two passages,“ There’s Still Gold in Those Hills” and “Letter From a Gold Miner” help the reader understand the history and process of Gold mining in the United States. Both passages give detailed information. They give specific instructions.They also give interesting background about Gold mining. These passages also give detail for different points of views. In the passage,“There’s Still Gold in Those Hills” it explains how gold mining works and the step to gold mine. For example…

A small western town, Libby Montana is known as the land of shiny mountains, originating from loggers and fur traders. Amongst the mountains is a 25-26 million year old volcano that was discovered to be a source of ore. Strip mines soon developed around 1923, providing well paying jobs for the citizens of the sleepy town. Zonolite merged with W.R. Grace and Company, becoming the the biggest employer of the towns men who pride themselves on being hard working and family oriented. These men worked…

HAILE GOLD MINE EIS The Haile Gold Mine Company desires to construct and manage a gold mine at an existing mining site in the state of South Carolina. The mine they are looking at was previously used to mine gold, but has been dormant for quite some time. The proposed mining site requires a permit from the U.S. Army Corps of Engineers (USACE). The USACE, a federal agency, has determined from early information that the proposed project could cause notable affects to the environment. Since the…

Flotation: To collect the gold, chemicals are added to the slurry to gather it into a concentrate form. The chemicals attach to certain minerals in the slurry and the slurry is then pumped into large tanks known as flotation cells. Air is then added to the bottom of the cells to rise through the slurry picking up the hydrophobic chemicals added earlier. Once it reaches the surface, it creates…

Magnesium is a mineral that can be described in so many different ways. It is almost impossible to name every little thing that magnesium may assist in to help our body function. To start with, magnesium is roughly involved in 300 essential reactions that happen within our body. The adult contains about 25g of magnesium in their body. Magnesium has specific recommended consumption level. If there is not enough magnesium in the body, it can cause multiple problems or illnesses. The same applies…

There are both similarities and differences between the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. One of the observed differences is that when the quartz is present at different temperatures. The α-FePO4 phase when present at low temperatures, tend towards the values obtained for β-FePO4 at high temperature. In addition, this case is true for all α quartz when at low temperature, in that it will tend to the values obtained for its respective β quartz experienced at…
