A mining feasibility study is an evaluation of a proposed mining project to determine whether the mineral resource can be mined economically. There are three types of feasibility study used in mining, order of magnitude , preliminary feasibility and detailed feasibility.
Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3600 tons annually, [1] and another 300 tons is produced from recycling. [2] Since the 20th century, gold has been principally extracted in a cyanide process by leaching the ore with cyanide solution.
Starting at level 71, players can unlock new Hero Talents for every class and specialization, providing more depth to character customization and combat strategies. [7] The Skyriding feature, initially introduced in Dragonflight as Dragonriding, allows players to explore the new zones at a fast pace while using various in-game mounts.
Currently, yearly gold mining produces 2% of the existing above-ground gold which is 158,000 tonnes (as of 2006). [119] In 2008, gold mining produced 2,400 tonnes of gold, official gold sales close to 300 tonnes, and dehedging (physical delivery of metal sold months before by mining companies on terminal markets) close to 500 tonnes.

For some games, grinding is an integral part of the gameplay and is required if the player wants to make significant progress. In some cases, progression may be entirely negated if the player does not grind enough, for example an area necessary for the story may be locked until a certain action is repeated a certain amount of time to prove the experience of the player.
For example, 99 tons of waste is generated per ton of copper, with even higher ratios in gold mining – because only 5.3 g of gold is extracted per ton of ore, a ton of gold produces 200,000 tons of tailings. [72] (As time goes on and richer deposits are exhausted – and technology improves – this number is going down to .5 g and less.)
24-carat gold is pure (while 100% purity is very difficult to attain, 24-carat as a designation is permitted in commerce for a minimum of 99.95% purity), 18-carat gold is 18 parts gold, 6 parts another metal (forming an alloy with 75% gold), 12-carat gold is 12 parts gold (12 parts another metal), and so forth.
