Question:

Process of iron ore mining?

What does the mining company do in terms of locating an iron-rich area and start their production? Any more info would be very helpful!

Answer:

First look in the right place. Most of the iron ore mined today dates form about 2 billion years ago when blue green algae transformed the atmosphere by producing excess oxygen which oxidized iron in the oceans causing it to precipitate out of solution. Thus a search for iron ore must start with rocks of the right age - found in Western Australia, Minnesota, South Africa, Minas Gerais in Brazil and other places. Further work might be an attempt to detect trends from other known deposits. Iron ore is not typically an isolated deposit but occurs in well known provinces. Iron ore is usually harder than surrounding rocks and typically forms hills - for example Mt Newman in Australia or the Mesabi Range in Minnesota. Identifying likely targets is a job for the photgeologist. Another way to identify targets is to use geochemical methods. For example a geologist may collect samples along streams. By combining the results from thousand of samples on a map it is possible to see anomalies where iron content is high and trace it back to a source. Or geophysical methods may be used. For example by flying a magnetic survey. Iron deposits create a magnetic anomaly. Or by flying a gravity survey. Iron ore is denser than surrounding rocks, so the force of the earth's gravity is slightly higher above iron ore deposits. Once targets have been identified, the only way to verify that iron ore is in sufficient quantity and quality is to drill. Finally a large sample may be necessary to convince blast furnace operators that the ore is suitable.
Sounds like static cling to me. You can buy these anti-cling sheets or calgon softener. Products like that.You just throw a couple sheets in dryer. BUT the white fuzz balls requires some manuel labor. Or buy a lint remover at walmart.Looks like an electric shaver. In laundry dept. I know. I have one . Works good. Takes a battery. Good luck.
It could very well be the nature of soft cotton and terry cloth fabric. But try this - be absolutely sure that you DO NOT use fabric softner, wash in cold water and with like colored cotton fabrics. Tumble dry on low heat only or air dry on a rack. You should also shake laundry loose after taking out of the washer and before placing in the dryer. Newer cotton products will shed for the first few washes.
