The diagram below gives an overview of the key processes involved in the refining of gold and silver Please note that this is highly simplified and does not detail the many sub-processes involved within each key process the chemical inputs involved in each process as well how the waste outputs from each process are handled Gold Refining Gold mines process ore using various techniques to
Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel Indeed it has been argued that iron ore is more integral to the global economy than any other commodity except perhaps oil

Iron is manufactured in a blast furnace First iron ore is mixed with coke and heated to form an iron-rich clinker called 'sinter' Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making Coke is
Yet mining the ore is just one stage in a long and complex gold mining process Long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well as how to extract and process the ore efficiently safely and responsibly
Another process involves ground ore being passed over plates which are coated with mercury The gold and the mercury form an amalgam leading to the name of the process amalgamation Once the amalgam has formed it is heated until the mercury gas is boiled off leaving the gold The mercury gas is highly toxic and must be handled carefully
The Copper Ore Mining industry is expected to expand at a largely steady pace over the next five years driven by forecast growth in copper ore output export demand and copper prices in US dollars Stronger global economic growth is expected to increase demand for copper over the period
Iron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
This process is excellent for silver and platinum group metals Silver is recoverable using this process but unfortunately it will not refine the silver We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely while also reducing costs

12 Chapter 11 -23 Types of Cast Iron Gray iron – 1 - 3 % Si 2 5 – 4% C – graphite flakes plus ferrite/pearlite – brittleness due to the flake-like graphite • weak brittle under tension • stronger under compression • excellent vibrational dampening • wear resistant Ductile (nodular) iron – a small amount (0 05 wt%) of Mg or Ce – spheroidal graphite precipitates (nodules)
The process culminates in an electric arc or blast furnace which renders the unwanted impurities into slag and allows the molten mixture to be cast into molds forming nickel pig iron The main advantage of the smelting process is that it is a proven technology and can process saprolite ores (high magnesium) in relative terms quickly
To make mining efficient and effective the raw rock and soil are typically not examined on-site Instead they are transported to special plants where the ore is processed and the rough diamonds are extracted Depending on how rich the ore is a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds

This is not enough to make it commercially viable to extract the rock Copper mines are only set up where there is more than 5kg of copper per tonne of rock (0 5% by mass) Ideally the figure should be closer to 2% The flow chart shows you how copper is extracted from its ore and converted into pure metal
Oct 05 2019However commodity producers always have variable revenues that depend on the price of the commodity they are selling In theory then investing in commodity companies is a way to make a leveraged bet on the price of the particular commodity As the commodity's price rises more revenues should flow to the bottom line in the form of profits
