3. What is milling? Why extracted materials should undergo milling process before refining them?

:please answer them correctly

Answers

Answer 1

Answer:

Explanation:

1-Exploration is an important step in finding minerals so they can be potentially mined. Our demand for minerals is increasing, for example we need more copper to build renewable energy assets such as wind turbines. This demand is helping drive an increase in exploration across the state.

2-In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

3-Milling

food processing

The flour milling process begins with cleaning the grain and tempering it by adding water. The tempered grain is ground in a series of rollermills to remove the bran and to cut the endosperm. Between each rollermill cycle, the ground grain is sifted and separated into various sizes. Middle-size material is sent to a purifier, or shaking sifter, and on to another set of rollermills for further reduction and sifting into a variety of flours and flour blends. These are then stored in large bins.

The fermentation and distillation process for producing whiskey. The production of whiskey begins with grinding grain into a meal, which is cooked. Malt is introduced to the meal, which results in mash that is cooled and pumped into a fermenter, where yeast is added. The fermented mixture is heated in a still, where the heat vaporizes the alcohol. The alcohol vapours are caught, cooled, condensed, and drawn off as clean, new whiskey. This liquid is stored in a cistern room, and water is added to lower the proof (absolute alcohol content) before the whiskey is placed in new charred oak barrels for aging and later bottling.In distilled spirit: Milling and pressing

Which layer of the atmosphere contains the ozone layer that blocks most of
the harmful ultraviolet radiation from the sun?
A. Stratosphere
B. Thermosphere
C. Mesosphere
D. Troposphere

Answers

Answer:

A. Stratosphere

Explanation:

The ozone layer, which blocks harmful ultraviolet radiation, is primarily located in the stratosphere, the second layer of the Earth's atmosphere. Therefore, option A is correct.

The ozone layer, which serves as a protective shield against harmful ultraviolet (UV) radiation from the sun, is primarily found in the stratosphere.

The stratosphere is the second layer of the Earth's atmosphere, located above the troposphere. Within the stratosphere, ozone molecules are formed and broken down through a natural process, creating a balance.

This ozone layer absorbs most of the sun's UV-B and UV-C radiation, preventing them from reaching the Earth's surface. This crucial role of the stratospheric ozone layer in shielding the planet from harmful UV radiation is essential for safeguarding ecosystems, human health, and the overall well-being of life on Earth.

Therefore, option A is correct.

What time will it be at 105W if it is 10pm, at 45W?​

Answers

Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360° ÷ 24 hours = 15° per hour).

To cover a distance of 1° (i.e., per longitude), the sun will take (60 ÷ 15 =) 4 minutes. Thus, the time difference per longitude is 4 minutes.

Thus, the time difference per longitude is 4 minutes.Now, between A and B, the number of longitudes is (90 - 15 =) 75. Thus, the time to cover 75 longitudes is (75 x 4 =) 300 minutes or (300 ÷ 60 =) 5 hours.

Now, since B (at 90W) is to the west of A (at 15W), time-wise, A is ahead of B, by 5 hours. So, if at A, the local time is 7 AM, the local time at B is (7 – 5 =) 2 AM.

2. How would you describe the process of mining based on this activity?

please answer correctly ​

Answers

Answer:

Explanation:

Many of the products we use everyday – from plastic water bottles to wrist watches and crayons to headphone wires – are produced from rocks and minerals mined from the earth. These rocks and minerals are considered a non-renewable resource because there is only a set amount of each and once it is used up, it will be gone forever. Some of these resources are very common and others are scarce. As the human population has grown, the demand for these resources has grown as well.

Extracting rocks and minerals from the earth is typically done by mining. Large scale mining operations are used all over the world and can often damage the

land on which they take place. Unfortunately, the

end result of mining (the profits made by selling the ore) can at times overshadow the damage done by the process (destroyed animal habitat, clear cutting of trees, pollution of local

streams, etc.).

Explanation:

Minerals used as ferroalloys such as chromium are essential to the production of specialty steels. Jet engines used in military aircraft are made of specialty steel. Political considerations can influence the import of resources from other countries. During the Cold War, communist countries such as the Soviet Union and China were not used as major suppliers of chromium because of military implications. Reset the map. Select Chromium Production by Country. Which of the following countries would be the best source of chromium for specialty steel production within the United States?
You did not open hints for this part.
a. South Africa
b. Brazil
c. Zimbabwe
d. India
e. Russia

Answers

Answer:

South Africa

Explanation:

During the Cold War South Africa was a major source of chromium for the United States. South Africa was considered the alternative to imports from the Soviet Union and the People’s Republic of China. Even though there was a world-wide embargo on South African commodities because of its policy of apartheid, the United States imported chromium from the world’s second largest producer. Even though Brazil is located closer to the United States, its chromium production is considerably less than that of South Africa.

The country that would be the best source of chromium for specialty steel production within the United States is South Africa.

This is because South Africa is known to have the highest deposits of chromium, with about 17,000,000 out of the 40,000,000 worldwide.

Also, South Africa was known to have supported the likes of the United States during the Cold War.

Options B and C are wrong because Brazil and Zimbabwe have no chromium deposits.

Option D is wrong because India stylishly supported the Soviet Union during the cold war; hence, they wouldn't have supplied the United States with the Chromium needed.

Also, option E is wrong because Russia forms the larger part of the Soviet Union, and till today they are still not on the same side in most political issues.

Hence, in this case, it is concluded that the correct answer is option A." South Africa."
