Although the "cement vein" was never found, many prospectors did find gold resulting in the mining camps of Dogtown, Mammoth City, Lundy Canyon, Bodie, and many others. It is also possible that the cement mine was rediscovered at some point during the last 150 years, without the finders knowing it. Lost Cement Mine Historical Marker.
But just as mining and cement need electrification in order to reduce emissions, electrification is equally dependent on mining and cement—it works both ways. Cement provides basic infrastructure for grids and also is the main component in the large, stable foundations needed for wind turbines. Mining is even more central to the equation.
This paper presents the feasibility of incorporating copper mine tailings (MT) as a partial substitute for cement in the development of concrete. The copper mine tailings used for this study have been accumulating for several decades at the tailings dump of Hindustan Copper Ltd. at Khetri, Rajasthan. Hence, alternative uses of MT need to be …
As society continues to become more urban we rely on cement, metals and minerals more than ever before. Our modern homes and offices, roads, power systems etc. would not exist without steel, copper, concrete and many other mined materials.
The precipitated copper is washed and drained into settling tanks. After the cement copper settles, the clear water is decanted and recirculated for leaching. The cement copper is further drained, air-dried to 15 percent moisture on …
The mining industry in India has to ramp up its efforts in order to be more energy efficient and sustainable. Since the process of mining plays an important role in cement manufacturing, we take a closer look at the impact of mining on the environment, human health and biodiversity, and the sustainable processes that are […]

Evolution Mining has entered into a binding agreement to acquire an 80% interest in the Northparkes Copper-Gold Mine in Australia.
Many studies have raised concerns that copper supply cannot meet the copper demands of both the green energy transition and equitable global development. This report addresses this issue by projecting copper supply and demand from 2018 to 2050 and placing both in the historical context of copper mine output.
The precipitation of copper from an aqueous solution of copper sulphate by scrap iron is known as cementation, because the precipitated metal is usually cemented …
The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody.
