in general there are two methods of vegetable/edible oil processing one is physical refining and the other is chemical refining. however no matter what kinds of reining methods they are all done with the help of various oil processing equipment and machinery and are used to refine almost all kinds of oil extracted from oil.
iron ore consists of oxygen and iron atoms bonded together into molecules. to create pure iron one must deoxygenate the ore leaving only iron atoms behind which is the essence of the refining process. to coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
at harder levels it is recommended two smelters because if one breaks down you can use the other to re-activate it. 3.8 when should i build a spew ===== as soon as possible because mpg can replace every other processed ore. 3.9 all my mines have run dry - what now
first the gold ore is crunched up into little pieces then a cyanide solution is used to dissolve the particles of gold. the remaining solid rock and other minerals are filtered out and the gold is precipitated out of the cyanide solution (this
some minerals require a physical and/or chemical process to remove them from the ore. large rocks containing minerals need to be crushed and milled. the valuable minerals are then separated from the rock using a variety of physical and chemical separation methods. people have extracted minerals for example iron and copper from ores for
there are actually a few different methods of refining gold. depending upon the quantity of gold you are working with and the desired level of purity the two most common methods for refining gold are the use of high temperature flame and the use of chemicals to refine the gold. refining with flame is one of the oldest methods of refining metals.
the details of the copper-refining process depend on the type of minerals the copper is bound with. copper ore that is rich in sulfides is processed via pyrometallurgy while copper ore that is
