Gold is obtained by two principal mining methods; placer and vein mining, and also as a by product of the mining of other metals. Placer mining Placer mining Placer mining is the mining of stream bed (alluvial) deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. en.wikipedia.org is used when the metal is found in unconsolidated deposits of sand and gravel from which gold can be easily separated due to its high density.

Gold flowed to the heart of the earth when the world was formed.
It is theoretically possible to document gold using nuclear processes involving fusion, fission, and radioactive decay.

Estimates indicate that between 2,500 and 3,000 tons of new gold is produced annually from all the average sources of gold in the world. Connoisseurs currently estimate the above-mentioned total amount of gold mined in the world at just over 190,000 piles.
How is gold mined or obtained
The process begins by drilling blast holes at least 40 feet deep, spaced 16 to 22 feet apart.
The bags are then continuously exploded to ensure minimal direct environmental impact.
The fractured rock will then be examined and marked to reveal ores containing this gold.
Where is gold naturally found
Gold is also found primarily as a pure household metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found in quartz veins or unwanted placers. It is said to be mined in South Africa, USA, Alaska), (Nevada, Russia, Australia and Canada).

How do we get gold from
Gold is undoubtedly mined from vein deposits by backfilling, blasting, raking, or surrounding fine gravel. Vein deposits often lie deep underground. To mine underground, miners drill shafts into the ground as they think. Then, using pickaxes and small explosives, they can remove the gold ore that has formed in the surrounding rock.
How is gold extracted from mines
cyanide process
Cyanide gold mining can be used in areas where good quality gold-bearing rocks are found. Sodium cyanide fixative is mixed with finely ground sand containing gold or silver and then separated from the ground rock as a fancy cyanide or jewelry cyanide solution.

Did the material obtained by the two groups look the same which group has obtained a material with magnetic properties can we separate the components of the material obtained on adding dilute Sulphuric acid or dilute hydrochloric acid did both the groups
Group I received material a with magnetic properties greater than one. The components of an article can be separated from group I only in a specific case. Yes, the groups are also given gas to add dilute sulfuric acid or hydrochloric acid.
When a number is successively divided by 4 & 5 the remainder obtained are 1 & 4 respectively when the same number is successively divided by 5& 4 the remainder obtained are *
When divided by 4, each number leaves a remainder, so its number must be 5, or 9, or 13, or even 17, or 21, and so on. For some of these numbers, the remainder becomes 1, and the quotient becomes a person, or 2, or 3, or exclusive, or 5. If the resulting quotient is divided by 1 by 5, the program leaves 4 as a remainder.
