Copper (Copper Recycling) is regarded as an important industrial metal due to its malleability, corrosion resistance, high ductility, and electrical and thermal conductivity. When it comes to metals used in the United States, copper ranks third, just behind iron and aluminum.
If you’re wondering if you can recycle copper, the answer is yes. Recycling copper is extremely important and valuable.
In the middle ages, the copper and copper alloy industries were dependent on the economic recycling of surplus products to use the most suitable and cheapest feedstock for making components that gives the most economic cost price for the material.
Both copper and brass has scrap values, you can easily recycle your copper scraps at any copper recycling near me/you and below are the scrap value for copper, brass and other copper alloys.
1) Bare Bright Copper
This is the most valuable grade is bright copper. The bright and bare appearance inspired the name. The copper wiring in this category must be at least 16 gauge.
This grade is sometimes referred to as Bright and Shiny Copper. This grade must not be combined or mixed with any other metal, including zinc or tin. The copper must be tarnish-free to qualify.
2) Scrap Value – Copper
Copper is one of the few metals that can be recycled repeatedly without any loss of performance.
Since the applied enamel layers are thin but they withstand voltage, they must have no surface flaws, the basis copper wire must have an excellent surface quality.
Uncontaminated recycled process scrap and other scraps that have been electrolytically refined back to grade A quality may also be helpful or used.

3) Scrap Value – Brasses
The impurities such as lead in brass are often required to improve machinability so such scrap is frequently acceptable.
When brass is re-melted, there are usually some evolutions of the more volatile zinc. This is made up in the melting process to bring it back within specification.
The zinc is evolved as an oxide that is drawn off and trapped in a baghouse and recycled for the manufacture of other products.
4) Scrap Value – Other Copper Alloys
Scrap has to be mixed, it is first re-melted by an ingot maker and analyzed so that the composition could be adjusted to bring it within grade for an alloy.
However, this only applies when the processing scrap arising within the copper works. Where copper has been contaminated and it is required to re-refine it, it is re-melted and cast to anode shape so that it can be electrolytically refined.
However, when fume is generated, for example by melting or welding, it may be necessary to use fume extraction equipment.
When alloyed with copper and are in a solid state, this presents no health hazard.
Copper consists of elements and minerals that are important for your everyday life.
Metals used in the United States are considered third-ranked copper, right behind iron and aluminum.

Brief History of Copper
During the early days when the discovery of copper was made that no degradation occurs during recycling.
The attributes of copper have ensured as one of the most valuable metals in the industry.
As technology improved, the discovery of melting ores was the very beginning of the Bronze Age.
Ancient Romans used copper from Cypress in the Mediterranean.
Economic and Environmental Importance of Copper Recycling
Copper recycling process offers significant benefits to our environment including its contribution in the reduction in energy required for processing, conserving natural resources, and decreasing the amount of solid waste sent to landfills.
Regarding recycling copper, the following statistics must be considered:
1. 85 to 90 percent less energy will be required for recycling copper than new processing.
2. The known copper reserves in the United States are about 1.6 billion metric tons.
3. 90 percent of the production of domestic copper comes from 20 mines.
4. Copper in the United States is mined in Montana, New Mexico, Arizona, Nevada, and Utah.
There are different grades of copper and below are the different grades of copper;
1) 1 Copper Grade
1 Copper is the second most valuable copper, this grade must be unalloyed and clean. The difference is clear, clean copper tubing is included in 1 Copper.
2) 2 Copper Grade
2 Copper is the third most valuable copper recycling.
3) 1 Insulated Wire Grade
This grade includes all clean copper cables and wires that have a minimum of 16 gauge.
4) 2 Insulated Wire
2 Insulated Wire is the fifth and last grade for copper recycling.
Benefits of Copper Recycling
The top three benefits are defined below.
1. Copper recycling helps in decreasing the cost of landfills: When your copper is not recycled, it takes up space in landfills thereby helping decrease the cost of landfills.
2. Copper recycling decreases the energy necessary for the production of copper by 85 percent: Copper is finite, meaning recycling conserves copper ore.
3. You can protect the environment the more by recycling more coppers and decreasing the need for refining and mining copper:
Mining requires energy, fossil fuels, and time. Refining copper releases toxic gases including dust and sulphur dioxide into the environment.

Copper Scrap Recycling Process Step by Step Guide
Copper is produced using a variety of smelting and electrolysis methods, with the end product being of extremely high purity.
Copper recycling methods consume 85 percent less energy than original smelting processes, though this does not account for the pretreatment process.
This procedure entails mechanical and chemical cleaning, as well as the separation of various components. It is critical that these processes remove impurities because extruding fine copper wires with imperfections in the base metal will cause stresses and fractures.
The scrap copper is compacted, baled, and transported to a smelter or designated copper recycling plant.
The bales are placed in an electric induction or reverberatory furnace with shredded pure copper. Sand and limestone are used to remove unwanted byproducts.
When the metal is molten, it is tapped or poured into various shaped molds and allowed to cool. The ingots or rectangular plates that result are electrolyzed, yielding 99.9 percent pure copper as the end product.
However, there are two basic methods for recycling copper at any copper recycling center near me/you:
1. Copper ore is melted at a copper smelter
2. Melting with a proportion of copper ingots at a copper recycling plant
Scrap copper and alloy components are loaded into the furnace at a copper smelter before it is fired up. The copper ore, along with the required amount of limestone and sand, is fed into the furnace.
When the mixture has become molten, it is tapped into rectangular molds using oxygen and air. The resulting rectangular plates are then electrolysis purified to 99.9 percent pure copper.
The furnace can be either electric induction or reverberatory in nature. The electric furnace melts all of the contents and tips the molten copper through a spout into molds for further processing or shipment to a copper smelter.
A reverberatory furnace is a square box structure lined with firebricks that is usually gas fired and has a front loading door that can be lowered or raised as needed. When the copper is molten, samples are taken, and the molten copper is poured into molds and allowed to cool.
The resulting copper ingots can be refined further or sent to a copper smelter for further processing.
1. The first metal ever worked by humans was copper followed by meteoritic iron and gold.
Copper has been used for about 10,000 years and more. An axe was made in 3300 BCE for Otzi the Iceman.
2. At that time when the axe was found, the head was made of almost pure copper.
It was said that this indicates the iceman was directly involved with the process of smelting copper.
3. The coloring of copper is metallic-reddish and unique. When copper is added to gold, the result is rose gold or red gold.
4. Copper is not toxic for invertebrates, which is the reason shop hulls often contain copper for preventing algae, and the attachment of barnacles and mussels.
5. Approximately 60 percent of all copper is used for wiring, electronics, cookware, plumbing, building construcion, coins, and various other products.
You most likely believe chlorine is what makes hair in swimming pools turn green, but it is copper.
6. Simple binary compounds are easily formed with copper.
The flame from Copper II is green, while Copper I result in a blue flame.
