Why aluminium is cheaper to extract than gold even though the extraction method is more complicated?
Bauxite ore is the base for aluminium and is more plentiful than gold ore. It is also cheaper to polish to the finished product. Aluminium has many more uses than gold so is readily adaptable to the consumer market. by Ruwayda :)
In industry cyanide are widely used during?
The extraction of gold and in electroplating of metals.
In industry cyanid compounds are widely used during?
The extraction of gold and in electroplating of metals.
What symbol of the element used to analyze ores for gold and silver?
The symbol of the element commonly used to analyze ores for gold and silver is "Hg," which stands for mercury. Mercury is used in various assay techniques, particularly in the amalgamation process, where it forms an amalgam with gold or silver, allowing for their extraction and quantification. However, due to its toxicity and environmental concerns, the use of mercury is being phased out in favor of safer methods.
What industries widely use cyanide compounds?
The main uses are the gold and silver extraction; also as precursor of nylon.
Who digs for gold?
Miners typically dig for gold in mines or rivers where the precious metal is naturally found. This process involves extracting gold ore from the ground and then processing it to extract the gold through methods like panning, sluicing, or chemical extraction.
Word equation for gold extraction?
The word equation for gold extraction using cyanide is: Gold + Sodium Cyanide + Oxygen → Gold Cyanide + Sodium Hydroxide.
Is there always gold in black sand?
Not always. While black sand can contain gold, it is not guaranteed. Large amounts of black sand may indicate a higher likelihood of finding gold, but it still requires proper testing and extraction methods to confirm its presence.
How was gold extracted in 1850 Australian gold rush?
Actually, the gold rush did not begin until 1851. Methods of extraction included panning, which was the most common method; cradling, which was introduced by Edward Hargarves after he saw the method used in California; puddling; and shaft mining.
How can we obtain gold?
Gold can be obtained through mining, either through traditional methods like open-pit or underground mining or through newer methods like heap leaching. It can also be obtained as a byproduct of mining other metals like copper or lead. Alternatively, gold can be acquired through purchasing it from dealers, investing in gold exchange-traded funds (ETFs), or buying gold jewelry or coins.
Why is Wiesel summoned to the dentist?
For the extraction of his gold crown.
How is gold taken out of the ground?
Mining, grinding, extraction or panning

In industry cyanide are widely used during?
The extraction of gold and in electroplating of metals.
What type of mining is used for gold?
Gold mining primarily involves several methods, with the most common being placer mining, hard rock mining, and by-product mining. Placer mining extracts gold from alluvial deposits in riverbeds or stream beds using techniques like panning, sluicing, and dredging. Hard rock mining involves extracting gold from ore deposits in solid rock, often using underground or open-pit methods. Additionally, by-product mining involves recovering gold as a secondary product from the extraction of other metals.
What metal is used to attract gold on the stamper tray?
Mercury is used to attract gold on the stamper tray in a process known as amalgamation. Mercury forms an amalgam with gold, allowing it to be separated from other materials during the extraction process. However, the use of mercury in gold extraction is hazardous to both human health and the environment.
