Phosphate mining operations in southeastern Idaho have exposed selenium (Se) that was originally sequestered in the subsurface. Sheep grazing in these areas have died as a result of high Se concentrations in forage and water. This study was designed to monitor

 · Selenium, a relatively rare element with diverse uses, is widely distributed within Earth''s crust, but it does not occur in concentrations high enough to justify mining solely for its recovery. Selenium is recovered as a byproduct of nonferrous metal ore processing, principally from the anode slimes associated with electrolytic refining of copper.

The Parys Mountain copper mining district (Anglesey, North Wales) hosts exposed pyritic bedrock, solid mine waste spoil heaps, and acid drainage (ochre sediment) deposits. Both natural and waste deposits show elevated trace element concentrations, including selenium (Se), at abundances of both economic and environmental consideration. Elevated concentrations of semi-metals such as Se in waste ...

Surface water Selenium (Se) concentrations are above regulatory standards at several active and inactive phosphate mine sites in the US Western Phosphate Resource Area. The focus of the present study was to examine the impacts of the microbial communities on the oxidation state of Se in overburden waste from the Smoky Canyon phosphate mine in Idaho, USA.

 · Feb 9, 2020. #1. I went through the Exigeous guide on farming G4 raw mats and now have maxed out these mats except for selenium. I can trade over to fill up that bucket with the other mats, but I want the option to farm selenium from known geo sites as well. I found a planet with a couple of flat areas and where each crystalline fragment drops ...

Finally, the regulations do nothing to require the long-term solutions that we really need: changes in mining practices to avoid selenium pollution in the first place. Mining companies come and go. Who will run these expensive water treatment plants for centuries

Selenium is a catalyst in some chemical reactions, but it is not widely used because of issues with toxicity. In X-ray crystallography, incorporation of one or more selenium atoms in place of sulfur helps with multiple-wavelength anomalous dispersion and phasing.

 · Locations on Planets to Find Selenium. You can use the crystalline fragments and needle crystals at Geological sites and the Polyporous Growths at Biological sites, anything else at both sites will almost certainly spawn much lower grade materials.

 · With new coal mines proposed for the Elk Valley, Sander-Green wants to see B.C. adopt a more stringent objective for selenium to ensure that the new limit is considered as part of the environmental assessment processes. Teck''s proposed Castle Mountain coal mine, now called the Fording River Extension Project, is also facing a federal assessment, which Sander-Green said will …

 · That 140-square-kilometre mining project has released large volumes of selenium and other chemicals into water supplies killing large populations of cutthroat trout and changing water quality ...

More about Selenium and how to get it. I saw where a poster found Selenium in a ring while mining, and saw an older post about mining without the refinery to get elements, and another that said it would be faster to go to the Barnacles. Others have said to do missions. Searching for Selenium with EDDB only shows planets with Selenium, not rings.

 · Selenium (Se) contamination in surface and ground water in numerous river basins has become a critical problem worldwide in recent years. The exposure to Se, either direct consumption of Se or indirectly may be fatal to the human health because of its toxicity.

 · Selenium is a slippery, multi-headed problem for mining. For starters, any technology has to treat large volumes of water to remove tiny traces of selenium. Any given wastewater can contain various selenium species with different solubility, toxicity and oxidization states that react differently to treatments and water temperature, and compete with other constituents.

 · Selenium enforcement is just one of the ways that the Club''s Environmental Law Program works to hold mining companies accountable for the true costs of their destructive and dangerous practices. While political leaders and regulators refuse to take action to stop mountaintop removal, citizens continue to push back against this destructive and harmful practice.

Selenium at the Gay Mine Area-Wide Selenium Investigations in SE Idaho In the mid-1990s, a naturally-occurring trace mineral called selenium, found in the "center waste shale" of phosphate mines (the rock layer found between layers of phosphate ore), was found to have leached into vegetation and waterways near mines in Caribou County, Idaho, at measurable concentrations.

 · Selenium Removal Technologies: A Review. Selenium has emerged as a water treatment contaminant of concern in industries such as mining, oil refining, and power generation.
