Mining

Iron ore typically comes from two main types of deposits: hematite and magnetite. Hematite ore is a reddish-brown ore that is high in iron content, while magnetite ore is a dark, black ore with magnetic properties. These ores are mined and then processed to extract the iron metal.

Some possible substitutes for talc in cosmetic products include cornstarch, rice flour, and arrowroot powder. These alternatives can provide similar absorbent and mattifying properties as talc without the potential concerns of talc contamination with asbestos.

You run the sand and gravel over different size screens depending on how many sizes you wish to sort the gravel into. In most large gravel pits, a deposit is sucked up with a pump (with water) through metal pipe up to a steel tower.Using gravity the sand,small pea gravel and larger gravels are separated. In most gravel pits the water turns green over time because of the Iron in the deposits.

I am gald to help you,my friend .

The electric motor makes the driver eccentric cause high speed revolving through triangle belt, The revolution eccentric has the very big centrifugal force, which stimulates sieves box to have circularmotion with certain oscillation amplitude. The materials on sieves receive the impulse which the sieves passing to produce continual throwing movement in the inclined screening surface, in the process of the material and the screening surface meeting ,it makes the pellet which is smaller than the mesh pass sieves, thus realizes the graduation.. Its law of motion is the circular or the ellipse line, the vibration source is the driver leading for the electric motor. The circular oscillation sieves is the single axle vibrator, the main axle fixed in sieves box makes fast revolving by the electrical machinery, the eccentric body installed on main axle makes rotation along with it, and causes the centrifugal force of inertia,which makes the sieve box that can have free vibration have the approximate circular trace's vibration.

Acid but not strongly acidic. Ph 7 is neutral, less is acid and more then pH 7 is alkali

Gold is typically mined through a process that involves drilling, blasting, crushing, and extraction. The ore containing gold is crushed and then treated with chemicals like cyanide to extract the gold. The gold is then purified through processes like smelting and eventually refined into a usable form.

Gold dust is finely ground gold particles, while gold sand contains a higher concentration of gold particles mixed with sand. Gold sand is often found in river beds or near water sources, while gold dust can be found in various geological formations. Both gold dust and gold sand can be panned or mined for gold extraction.

I wouldn't think so! Usually the deed that the owner has includes mineral and other resources. If you want to mine gold there, you would have to make an agreement with the landowner as to how the mineral would be extracted, the royalties you would pay and so on.

The mining method used to mine iron ore depends on the placement of the ore body and surrounding environment. - Addition below I would say the majority (over 95%) or iron ore mines are open cut. /BL

Some common ways of separating mixtures include filtration (based on particle size), distillation (based on differences in boiling points), chromatography (based on differences in solubility), and evaporation (based on differences in volatility).

Nickel is typically mined from nickel sulfide ores or laterite deposits. The extracted ore is then processed through various techniques such as smelting or hydrometallurgical processes to extract the nickel metal. The final product is usually in the form of nickel cathodes or nickel powder.

Antique brown granite countertops can be sourced from countries such as Brazil, India, and Norway. These countries are known for producing granite with unique patterns and colors that are popular in the countertop industry.

Copper chloride is commonly found in pesticides, fungicides, pigments, and as a reagent in chemical reactions for laboratory use. It is also used in the production of wood preservatives and as a catalyst in organic synthesis.

To use a pick for gold mining, swing it to break up hard rock or compacted soil to reveal gold-bearing material underneath. Use the pick to chip away at the material and collect any visible gold using a gold pan or other equipment. Be mindful of safety precautions and local regulations while mining for gold.

Antimony is primarily found in China, Russia, Bolivia, and South Africa. It is typically mined as a byproduct of other metals such as lead, silver, and zinc. Antimony is also found in trace amounts in some ores and minerals.

Copper and gold; copper is brown when in a pure state (green is more familiar, but that's actually an oxidized copper), and gold is yellow.

Mining titanium can have positive economic impacts, such as providing employment opportunities and attracting investment to the region where mining occurs. However, it can also have negative impacts, such as environmental degradation, displacement of communities, and potential conflicts over land rights. It is important for governments and companies to balance the economic benefits with the social and environmental costs of titanium mining.

Titanium is found as an ore in several locations, from Africa to India, to Canada, in deposits of the ores rutile and anatase (titanium dioxide), and ilmenite (iron titanium dioxide).

Australia, South Africa, Canada, Norway, China, India, and the Ukraine all have commercial titanium mines, and Vietnam is developing a refining capacity as well.

Senegal, Cote d'Ivoire, Mozambique, and Madagascar are also mining titanium, and are expected to become leading producers within a few years.almost no certain location

copper, silver and carbon are not real ores but could be found as pure elements: carbon as coal, or diamond. Silver as nuggets. Copper as native copper specimen. Iron is almost never found in the free elemental state, and should be extracted from iron ore, which is not iron, but mainly made of iron oxides.

Pyrite can form in a myriad of different crystal habits. Primary pyrite habits such as framboid, colloform and spheroidal textures are those most often associated with growth in soft sediments. Cubes and the more characteristic forms are associated with increased P-T conditions and recrystallisation. So, the reason pyrite has many shapes is because it can be found in virtually every rock type, it is generally rigid and stable at temperatures up to ~743 degrees and so throughout its history it will be affected by a number of different factors which may alter crystal forms. Why and how certain textures grow is still contentious

Silver is found in native form, as an alloy with gold (electrum), and in ores containing sulfur,arsenic, antimony or chlorine. Ores include argentite (Ag2S), chlorargyrite (AgCl) which includes horn silver, and pyrargyrite (Ag3SbS3). The principal sources of silver are the ores of copper, copper-nickel, lead, and lead-zinc obtained from Peru, Bolivia, Mexico, China,Australia, Chile, Poland and Serbia.

In Michigan, Nevada, and Arizona. Out of the U.S. - Canada, Mexico, Peru, Bolivia, and Australia.

Some mining is done by scraping away the soil (dirt) from the top of the ground. This is called strip mining. Some mining is done by going deep underground into a mine shaft. Some mining, such as gold mining, is done in other ways. Gold can be mined by searching in the bed of a river or other stream of water to remove the flakes of gold. This is called panning or placer mining.

Quartz is found in many countries around the world, including Brazil, the United States, Russia, and Madagascar. It is a common mineral that can be found in various geological formations and environments globally.

Carbon is not mined like other minerals. It is primarily obtained from fossil fuels such as coal, oil, and natural gas through extraction and refining processes. Carbon can also be extracted from biomass sources such as plants and trees through methods like pyrolysis.
