Cobalt is a ferromagnetic metal and it is not found naturally in its pure form but in its compounds are found in most rocks ,soil, plants and animals. Due to its weakly reducing nature it is used mostly in oxidation.

What is cobalt Ore

Cobalt is a weakly reducing metal that is protected from oxidation by a passivating oxide film. It is attacked by halogens and sulfur. Heating in oxygen produces Co3O4 which loses oxygen at 900 °C to give the monoxide CoO. The metal reacts with F2 at 520 K to give CoF3, with Cl2, Br2 and I2, the corresponding binary halides were formed. It has no reaction with H2 and N2 even when heated, but it does react with boron, carbon, phosphorus, arsenic and sulphur. At ordinary temperatures, it reacts slowly with mineral acids, and very slowly with moist, but not dry, air.

Its Uses and Consumption

Lithium cobalt oxide is used as an electrode in lithium batteries. Rechargeable NiMH batteries also contain some cobalt.

Paints, varnishes and inks can be made with cobalt if a certain color is needed.  It may be possible to create a nuclear bomb using cobalt-59. The blast would be very small but the area would be contaminated with radioactive waste for some time.

Cobalt-60 is used in medicine as it produces gamma rays. These are used in radiotherapy, sterilizing medical supplies and waste, sterilizing food and measuring the density of an object.  Cobalt-57 is also used in medicine. It can be used to work out how much vitamin B12 is being taken in by the human body.  The ground coats for porcelain enamels are made from cobalt.

Some jewelery and cutlery are electroplated (coated) with cobalt as it is hard and resistant to oxidation.

cobalt2Extraction of Cobalt Ore from other metals.

Since cobalt does not exist on its own there are different methods that are used to separate it from copper and nickel depending on the concentration of cobalt and the exact composition of the ore used.

When it is being extracted from copper the ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble oxides and iron into soluble hematite. When being separated from nickel sulfide concentrates it can be treated by either roasting of flash melting to reduce matte from which nickel and cobalt can be recovered hydrometallurgically. apart from these two concentrates it is also separated from other ore like arsenide ores, and laterite and then it is purified either by electrolysis or other methods.

cobalt3Why work with More Than Conquerors Company? The reasons are many.

Today, many organizations are under extreme pressure to optimize Commodity Sourcing in mining and exporting them to different parts of the world. Mining and exporting minerals needs companies to improve and manage the available resources by focusing energy on the core competencies of the technologies and achieving a more efficient service/product at a lower cost and with quality products.

More Than Conquerors Company is committed in providing our clients the basic function as international mining and exporting specialist role we perform virtually to every activity necessary to assure the quality mining and exportation and purchasing at the most favorable price, quality and conditions from the first step in mining and delivery point to final destination port at the lowest cost in the shortest possible time.

cobalt4In this rapidly changing mining and export world more than Conquerors Company strongly believed that we bring value to our clients by maximizing cost-effective solutions in exporting the commodities among other services that entail the overall process involved in our transactions. We align ourselves with reliable partners who provide effective services both locally and internationally.

As a company providing mining and export services for our clients, we continually maintain existing and develop new supply relationships, while performing extensive due-diligence on our suppliers to maximize buy-side resources while insuring service performance and total customer satisfaction, thereby lowering the cost of each transaction.

We work with different types of clients and in all this our attention to mine the products and products we offer continues to be a major factor in building our reputation and our ever increasing client and partner relationships. We have direct relationships with minerals and exportation systems. Our reputation with both the service providers and the clients is very important to us and we will not compromise this under any circumstance and our policy of partnerships is very clear. In simple terms we work to achieve sustainable long term business relationships which benefit our clients and our partners.

Currently we have long-term contracts obligation of mining the commodities and in particular in ore which has many reliable product across the world and the clients have faith in our delivery systems.
