Mining

No, it is not flaky . it is calcium carbonate , a sedimentary rock. it's made of shells of animals.

Iron pyrite is universally known as "Fools Gold". It does bear an astonishing resemblance to gold, but it is merely a sulfide of iron, nonetheless.

Mercury was used in gold mining because it could bind to gold particles, forming an amalgam that allowed for easier extraction of gold from ore. However, this method resulted in significant environmental pollution due to the release of mercury into waterways and ecosystems.

Australia is considered the country the most rich in uranium ores.

Pyrrhotite is typically mined using underground mining methods, such as shaft mining or drift mining. The ore is extracted using drilling and blasting techniques to access the pyrrhotite deposits embedded in the rock. Once mined, the ore is processed to separate the pyrrhotite from the surrounding material.

Michigan's upper peninsula is known for mining copper

Miner's lamps (and spelunkers, too) utilize a compound commonly called Carbide. It is a lumpy product, which, when water is dropped onto it, releases acetylene gas. The gas is ignited (usually from a spark wheel mounted on the lamp's reflector) to provide light.

Australia has an abundance of uranium due to its unique geology and mineral-rich landscape. It is estimated that Australia holds about 30% of the world's known uranium resources, with approximately 1.4 million tonnes of uranium oxide.

An aggregate is a collection of minerals or particles that are combined together naturally, while an ore is a rock or mineral deposit that contains a valuable substance that can be mined and processed for profit. In simpler terms, an aggregate is a natural collection of materials, whereas an ore is a specific type of material with economic value.

Well this is the part where i start acting like a nerd.

HI MY NAMES JACK HARRISON AND BASICALLY THERE IS 25 METALS IN HEMATITE AND A GREAT BIG BRAIN BELONGING TO A CRAB

Yes, they can. Sand is almost all oxides of silicon, and it won't react with water. There is no "danger" associated with filling a container with sand, adding water to cover it, then snapping on a lid. If you'd like to use a mason jar with a screw on lid, go for it. Just don't let either container freeze or allow it to get too hot, as freezing or boiling water expands and creates pressure.

Limestone can be found in various locations worldwide, including the United States, China, and the United Kingdom. Sandstone is also widely distributed and can be found in places like Australia, India, and the United States. Both types of rock are commonly used in construction and as building materials.

Quartz is a durable and low-maintenance material that is resistant to stains and scratches. It comes in a wide variety of colors and patterns, making it easy to find a style that fits your design preferences. Additionally, quartz is non-porous, which makes it hygienic and resistant to bacteria growth.

The value of black amethyst can vary depending on factors such as size, quality, and demand in the market. On average, black amethyst can range in price from $10 to $50 per carat. It is recommended to consult with a reputable jewelry appraiser or gemologist for an accurate valuation.

Diamond mining has been documented since at least the 4th century BC in India. Modern diamond mining began in the late 19th century with the discovery of diamonds in South Africa, sparking the diamond rush.

'Pyrite' is the name of many minerals found on Earth. The most common and famous is 'Iron Pyrites', or 'Fool's Gold', because, to the untrained eye, it looks like gold. However, its appearance is slightly cuboid, where as true gold is more rounded in appearance.

Afghanistan is known to have rich deposits of various minerals, including natural resources such as copper, iron ore, gold, and rare earth elements. These resources have the potential to significantly contribute to the country's economy and development.

Yes, magnetite is worth mining because it is a major source of iron ore. It has high iron content, making it valuable for steel production. Additionally, magnetite is used in various industrial applications such as magnetic materials and as a pigment in paints.

Diamond and graphite are polymorphic - minerals with the same chemical formula but of different crystal structure. Both are made only of the element carbon. Because they form under different conditions of temperature and pressure, their crystal structure arranged differently. Hence, the vastly different physical properties.
Diamonds and graphite are separate allotropes of carbon, different because of their atomic structures. Carbon formed as diamond is the hardest mineral on earth.

It is initially done manually. In that you pick out the gold from the other rocks.

After that there are various acids and chemicals that dissolve the gold and separate it from the other material

Gold ore is a naturally occurring rock that contains gold in its elemental form, whereas gold nuggets are small pieces of pure gold that have been eroded from their original source and typically found in stream beds. Gold ore needs to be processed to extract the gold, while gold nuggets are already in their pure form and ready to be used.

Iron is typically extracted from iron ore, which can come in various forms such as hematite, magnetite, and taconite. The most commonly mined iron ore is hematite, which is rich in iron oxide. This iron ore is processed and refined to extract the iron metal.

Only one place - where it is mined in Ontario, Canada. Read on for more Nickel info: Nickel was discovered by the Swedish chemist Axel Fredrik Cronstedt in the mineral niccolite (NiAs) in 1751. Today, most nickel is obtained from the mineral pentlandite (NiS·2FeS). Most of the world's supply of nickel is mined in the Sudbury region of Ontario, Canada. It is believed that this large deposit of nickel ore is a result of an ancient meteor impact.

Nickel is a hard, corrosion resistant metal. It can be electroplated onto other metals to form a protective coating. Finely divided nickel is used as a catalyst for the hydrogenation of vegetable oils. Adding nickel to glass gives it a green color. A single kilogram of nickel can be drawn into 300 kilometers of wire. Nickel is also used to manufacture some types of coins and batteries.

Now how about that ?

Yes, limestone is used in both processes. In smelting iron ore, limestone acts as a flux to remove impurities from the ore. In cement production, limestone is one of the main ingredients, along with clay or shale, to make clinker that is then ground into cement.
