Copper: The most inexpensive and extremely useful metal

Copper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization. The common uses of copper in the construction field include using it for welding and soldering; use in brazing applications; use for making lightning rods; and, use in plumbing applications (like making pipes and fittings from copper). The use of copper has also been promoted in the modern concept of green houses and green buildings. Copper is a relatively inexpensive and extremely plentiful metal with numerous useful properties. It effectively resists corrosion and is a very effective conductor of both electricity and heat.

Currently, copper is used in building construction, power generation and transmission, electronic product manufacturing, and the production of industrial machinery and transportation vehicles. Copper wiring and plumbing are integral to the appliances, heating and cooling systems, and telecommunications links used every day in homes and businesses. Copper is an essential component in the motors, wiring, radiators, connectors, brakes, and bearings used in cars and trucks.

Over the past few years, there has been a great demand of copper suppliers all around the country. The rise in their demand is majorly because of the growing demand of copper and also because of the depleting copper resource from the earth's crust. However, its total reserve in the earth’s crust is still too much to be exhausted and they would last centuries.

A Guide To Filtering Copper Carbonate

Copper carbonate is the name given to a blue-green powder that is used as a colorant in paints and fireworks, as a fungicide and algaecide used to keep home aquariums clean and is found in trace amounts in animal feeds. To create this substance, you will need to create a solution that combines aqueous sodium carbonate heptahydrate and aqueous copper sulfate; it will precipitate out of this solution if you have completed the process correctly.

Step 1: Weigh out 100 grams of sodium carbonate heptahydrate using a set of accurate scales. Then, weigh out 100 grams of copper sulfate, using the same set of scales and cleaning to prevent cross-contamination.

Step 2: Place the sulfate in a 500 milliliter beaker and add around 200 milliliters of hot tap water. Swirl to combine the liquids adequately.

Step 3: Place the heptahydrate into a beaker and add around 200 milliliters of room temperature water. Stir until it dissolves (you may also slightly heat it).

Step 4: Line a funnel with some filter paper and place it over the top of an empty beaker. Set this aside for later use.

Step 5: Stir the heptahydrate solution into the beaker with the sulfate solution using a glass stick. Leave to stand for a period of between 1 and 12 hours, making sure that you agitate the mixture periodically. The copper carbonate should form and drop out.

Step 6: Pour the solution into the empty beaker through the funnel, making sure that you keep the carbonate suspended. If you let it pass through the funnel, you are wasting the precious substance.

Step 7: Leave the solution to stand for another 12 hours, then filter again through a fresh filter, making sure that you keep the carbonate suspended.

Once you are finished, you should have completely separated the solution and the copper carbonate. If you plan on letting the mixture sit overnight, you can keep it agitated by placing the beaker gently onto a shaker. Because you are working with potentially dangerous chemicals, it is important that you wear safety goggles and gloves whenever you are working with the solution, just in case you spill it.
