The sorter was then tested by Michigan Technological University on native copper ores. In these tests larger size ore (minus 4 plus 2 and minus 2 plus 1 inch) was sorted, and a high average recovery ( pct) was attained. Electronic Ore Sorting Machines Belt Sorter. Belt sorters (fig. 1) were used in both parts of the experimental program.
The ore is crushed and stacked into specially designed pads. The pads are lined with synthetic or natural materials such as polyethylene or compacted clay. Acids are introduced to copperbearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that “leaches” through the rocks is collected.
Sep 18, 2019· Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

Roofing copper is another type of copper that is generally always separate from 1 and 2 copper. Roofing copper is usually valued much lower because of the amount of tar and/or paint that is on it. When processing roofing copper for reuse, the paint and tar have to be burned off and it is a much more involved process.
The Electrolytic Separator sends controlled amounts of direct current into a fluid, causing the atoms in the fluid to break their bonds. This process of electrolysis is used to create some very useful gases from some rather ordinary fluids.. The Electrolytic Separator requires a constant supply of power and must have a source of a suitable liquid in order to produce the gases.
Extracting of Copper from Other Ores. Copper can be extracted from nonsulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the hightech, and are applied to a variety of materials, including aluminum, iron and copper.

I have iron and copper deposits touching on the map. Mines that can pull from any overlapping tile produce 2 kinds of ore. There is a lot more copper, and I have been struggling to think of a good, highthroughput way to sort the ores from each other. (It's my second world, new, I don't have much tech yet, but do have splitters, and smart inserters.)
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

May 04, 2008· The solid was a mixture of Cu and unreacted Fe. The problem was that we couldn't exactly separate the two metals (the iron filings were picking up the copper (tried separating with a magnet), as we ground the clumps with a mortar and pestle. What I'm asking you guys is is there any way to (fairly quickly) separate the iron and copper? Thanks!

Extracting copper from other ores. Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
Optical sorting and lasers are very well suited to the detection of ores with different colours, such as copper oxide, or crystalline structures in quartz. By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations.

After classification, ores are sent to the magnetic separator. The magnetic substances will be separated from the mixtures by magnetic force and mechanical force, because various ores have different specific susceptibility. Going through the primary separation by magnetic separator, the ore particles are sent to flotation separator.
The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.
