Whether the metal makes the aluminum can that you drink out of or the copper wires in your computer, it started out as an ore. But the ore's journey to becoming a usable metal is only just beginning when the ore leaves the mine. Mining produces a mixture of rocks that contain ore and other rocks that do not contain ore.
The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted ...

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two categories- manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the ...
To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.
Nov 12, 2012· In this video we are crushing some rocks we have collected from various prospecting trips and even a couple from landscaping beds from all over. The goal is to find some gold in it.
Other hardrock mines are large strip mines that remove the surface dirt and rock and then extract the ore from the resulting open pit. Removal of ore is often accomplished explosives, enormous power shovels, and massive trucks, some capable of carrying 500 tons of rock in one load.

Rock and other waste materials removed as impurities when waste mineral material is separated from the metal in an ore.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
Removal of other elements: Elements like phosphorus and silicon react with the oxygen to form acidic oxides. These are removed using quicklime (calcium oxide) which is added to the furnace during the oxygen blow. They react to form compounds such as calcium silicate or calcium phosphate which form a slag on top of the iron.
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

If you do find a rich pocket, you may be interested in methods to crush and extract the gold from you high grade rock. You can find my webpage on that topic at Hand Crushing Rich Ores: If you have a rich quartz vein or other hard rock deposit, you may be interested in the mining methods used to mine and break the rock. Its hard to believe, but ...
Surface mining; Open-pit mining is used if near-surface ore body is massive or when it occurs in steeply-dipping lode(s), sheeted vein systems, pipes, or makes up the bulk of the country rock as in disseminated or prophyry-style deposits. The whole ore body is mined with no overburden being put back into the void during the extraction operation.
Mar 13, 2018· You can't actually melt gold from rocks; if you hold a rock over a flame hot enough to melt gold and expect the gold to dribble out, you're going to be disappointed. The process of extracting gold from ore is a multistep one, and historically it has involved the use of some dangerous chemicals, including cyanide and mercury.
Small, gas-powered smelting furnaces can also be used to separate metal from ore. A cylindrical sheet metal container is built over a gas flame (propane can also be used). Then, a network of tubing is fitted around the smelter. The tubing includes a gas line, an air line, and other piping.
No matter which crushing system you're using, the process will go far faster, and come out better if you do repeated screenings of the material from time to time. What happens in crushing is that some of the material gets crushed down to the size you want but other pieces don't.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal.

Mining allows you to find and mine minerals, ores, and stones from resource nodes and certain mobs (see Ore skinning) scattered throughout the world. It is one of the primary professions. Materials from mining and the items miners can create from them are reagents needed for recipes within other …
Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.
