Michigan's UP is full of closed mines. Technology may give

Funded by a $50,000 grant from the Alfred P. Sloan Foundation, a two-year pilot project will focus on the Mather B iron mine, which closed in 1979 and whose former administrative offices are now a high school. The idea is to novelly use the contours of underground mines to harness time-tested technology: pumped hydro storage. Get price

Selenium Removal Technologies A Review

Jan 15, 2016Iron co-precipitation effectively removes selenite but removes very little selenate. This process has been widely used at mine sites, and typically requires clarification and filtration downstream of the co-precipitation process, as it generates large amounts of sludge. Get price

How Mining Companies are Reducing the Environmental Impact

Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can't go on this way, and politicians agree. It's why mining companies are working to reduce the environmental impact of mining through [] Get price

Hurstwic: Iron Production in the Viking Age

The iron ore shown to the right was excavated from Skgar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt. Get price

Iron Ore and Pellets

Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and appliances. Get price

Innovations: Introduction to Copper: Mining Extraction

However, by far the greatest extension in the use of copper resulted from Michael Faraday's discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity. The same principle was used to develop electric motors. The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by Thomas Edison in 1879. Get price

What Were Some of the Tools That Were Used in the Gold Mines?

Sep 29, 2017Stamps were used in California gold mines around 1850. First developed in England and used by Cornish miners, stamps were heavy iron machines used to pound rocks containing gold quartz into a fine dust so the gold ore could be extracted. Small stamps were commonly powered by water wheels while larger ones ran by steam engines. Get price

Iron Mining Process

Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. Get price

GEOPHYSICAL METHODS IN EXPLORATION AND MINERAL

used in mineral investigations to map low-velocity alluvial deposits such as those that may contain gold, tin, or sand and gravel. Applications in geoenvironmental work include studying the structure, thickness, and hydrology of tailings and extent of acid mine drainage around mineral deposits (Dave and others, 1986). THERMAL METHODS Get price

Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice. Get price

Minerals, Precious Metals and Gems

It is a brittle metal and resembles iron. Fluorite (fluorspar) is commonly used to create fluorescent pigment and since it is very beautiful, it is used for gem material. It is mined all over the world. Gold is the most familiar metal to most people. It is used for jewelry, Get price

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms. Get price

ANCIENT MINING

When mining hard stone, an iron gad (a pointed bar) struck by a hammer would remove stone in flakes and dust. This gad could be socketed for a handle, held in miners' hands, or gripped with tongs [Davies, p. 32]. The Romans used single and double headed hammers weighing 5-10 pounds, with sockets for a wooden handle [Healy, p. 100]. Get price
