Have you ever wondered what a modern gold mine looks like Take a look.
So how do we get to the gold The gold that is left at Haile after nearly 200 years of mining is found in the ore body below the ground.
During this phase of our operations we are using open pit mining which is what it sounds likewe make open pits in the ground and haul the ore out to be processed and the gold removed.
Mine pits are being opened to various depths in a process that involves mechanically removing the softer overlying soil and blasting loading and hauling away the overlying rock to reach the gold ore A series of pits will be opened mined and reclaimed in sequence.
It takes a lot of rock to get a little gold First the pit walls must be sloped back for the safety of the workers Then there are wide roads to get very large equipment in and out safely Once we reach the ore it takes 20 tons of rock to produce one ounce of gold Yes 20 tons.
The gold bearing ore from the mine pits is processed by crushing grinding concentrating and recovering the gold and then smelting it into dor bars These bars are a semipure alloy of gold usually about 90 gold Theyre then refined into pure gold.
The ore processing facility also known as The Mill 8211 includes processing facilities chemical storage facilities spill containment structures a water treatment plant.
Chemicals and reagents including sodium cyanide are used in the processing of gold Some of these chemicals need to be managed carefully so they will be stored in specially designed facilities and managed to prevent their release to the environment.
Gold ore can be mined at level 40 Mining providing 65 Mining experienceAfter a gold rock is mined it will take 60 seconds until it reappears Gold ore is the raw material used to smelt a gold barSmelting gold ore into a bar gives 225 Smithing experience or 562 with the goldsmith gauntlets equipped Since smelting gold bars is an easy way to gain Smithing experience gold ore is often.
How to separate silver from gold oregt Feb 24 2013183 was351 Depending on gold to silver ratio content of the metal the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold.
Gold processing preparation of the ore for use in various products.
Gold Au melts at a temperature of 1064 C 1947 F Its relatively high density 193 grams per cubic centimetre has made it amenable to recovery by placer mining and gravity concentration techniques With a facecentred cubic crystal structure it is characterized by a softness or malleability that lends itself to being shaped into intricate structures without sophisticated metalworking equipment This in turn has led to its application from earliest times to the fabrication of jewelry and decorative items.
Endogenetic gold ores include vein and lode deposits of elemental gold in quartzite or mixtures of quartzite and various iron sulfide minerals particularly pyrite FeS2 and pyrrhotite Fe1xS When present in sulfide ore bodies the gold although still elemental in form is so finely disseminated that concentration by methods such as those applied to alluvial gold is impossible.
Native gold is the most common mineral of gold accounting for about 80 percent of the metal in the Earths crust It occasionally is found as nuggets as large as 12 millimetres 05 inch in diameter and on rare occasions nuggets of native gold weighing up to 50 kilograms are foundthe largest having weighed 92 kilograms Native gold invariably contains about 01 to 4 percent silver Electrum is a goldsilver alloy containing 20 to 45 percent silver It varies from pale yellow to silver white in colour and is usually associated with silver sulfide mineral deposits.
2 Ore and Waste Rock Removal Once the ore metalbearing rock and waste rock have been blasted into smaller blocks and fragments mining facilities use excavators to remove the ore and waste rock from the ground and load the ore and waste rock into haul trucks for transport out of the mine pit.

Gold ore is a type of ore that can be obtained by mining gold ore rocks requiring a Mining level of 40 or higher and granting 65 experience Gold ore can be smelted into gold bars through the Smithing skill requiring level 40 Smithing Gold bars can then be crafted to make various pieces of jewellery.

In all experiments aimed at testing the gold content of rocks or ore you should ask yourself whether the conditions of his test differ in any vital particular from those that would obtain on a commercial scale if so there is no guarantee that his results would be borne out in a working plant Small scale experiments are very valuable if carefully and skilfully performed but may be.
