Mining

Factors that can affect soil erosion include steep slopes, intense rainfall, lack of vegetative cover, poor soil structure, and human activities like deforestation and agriculture practices that disturb the soil. These factors can increase the likelihood of soil being washed or blown away, leading to erosion.

Arkansas is the US state out of which come the most diamonds. The United States just doesn't have the "right geology" to have diamonds as a natural resource. Diamonds usually come from or appear near (having washed out of) kimberlite pipes. The geology of the US is broad and breathtaking, but does not include much in the way of these unique geologic structures.

No; iron ore is mixed with copper and smelted; the ore needs to be refined to extract pure iron.

You cannot make a tool out of ore, but rather with pure iron.

The Railroad Co. misused the government land grants, which the railroads sold to other businesses rather than to settlers, as the gov. intended to do. The railroads also entered into formal agreements to fix In_what_ways_did_the_railroad_companies_use_their_power_to_hurt_farmers, which helped keep farmers in their debt.

Platinum is rarely found on its own, but in combination with other base and precious metals. Extraction of the pure metal from ores is a complex process, and includes milling the ore, a froth floatation process, and smelting at high temperatures. This removes base metals, notably iron and sulfur, and concentrates PGM- platinum group metals- gold, platinum and palladium. The PGM matte is further processed by electrolysis to remove nickel, copper and cobalt. The high grade concentrate is treated by solvent extraction, distilling, and ion exchange treatment to separate the PGMs into its separate metals.

Sandstone is a sedimentary rock made up of sand-sized grains of minerals or rock fragments. It can vary in size, from very fine to coarse grains. It is called "sandstone" because of its predominant composition of sand-sized particles that are compacted and cemented together over time to form the rock.

Quarry tile is a tile made from clay and shale. It is very dense and often comes un glazed. It is a very natural looking tile.

Mining brought people west because people wanted gold. They also wanted to get rich quick. But a good miner would get ten cents a day. The miners did not rich the merchants got rich because people bought from the,.

Silicon is commonly used in the production of semiconductors for electronic devices, such as computers and smartphones. It is also used in the manufacturing of solar panels, glass, and ceramics. Additionally, silicon is used in the construction industry for producing concrete and sealants.

Technology has changed this in our time. Machines now do the job for us. Computers and radar and sonar have made finding minerals easy today. However, there are still a need for manpower to make sure that the mining process goes into success. Thankfully and compared to before, there are now a lot of safety equipment and training programs along with rules and guidelines that helps workers keep themselves away from danger.

Gold is mined at Kalgoorlie. They have a big "super pit" and they are still mining gold today.

Mining has been going on for 8,000-5,000 years.

Stop using explosives, stop surface and subsurface mining, and start recycling
