WHAT WE DO


Coltan Mining Limited supplies and processes various minerals and metal ores for extensive industries.
Also some of our processed solid minerals are used for bond markets, LME, LMBA and others. We also invest in sustainable infrastructure projects, renewable energy, roads, hospitals, schools and housing in Africa and Latin America.

Please see below the minerals / metal ores we are able to provide wrought / un-wrought


Coltan

COLTAN (Columbite-Tantalite)

This is a dull metallic ore we mine in major quantities in the Latin America, America and Africa.

The Ta205 / 6 content is usually between 20 – 60% coltan is widely known for its superconductive properties and as a result is highly prized in aerospace industry and much more.

We can provide from 1 – 100 MT per month all of our Coltan is sampled, weighted assayed and packed Before shipping.

 

Tantalite
Tantalite is black to brown in both colour and streak. We also provide manganese rich tantalite’s which are brown and translucent in appearance.

 

Tantalum
Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion resistant. We supply for laboratory equipment and a substitute for platinum to companies such as mediquip.
CM Ltd manufactures tantalum capacitors for electronic equipment such as mobile phones, DVD players, video game systems and computers.

 

Niobium
Niobium is a, lustrous grey, ductile metal
We provide Niobium for cryogenic industries manufacturing and producing liquid nitrogen for fuel etc. in addition to this we provide alloys, for special steel use in gas pipelines. Our Niobium is utilized in jet and rocket engines and superconducting magnets for MRI scanners.

 

Gold ore and Ingot bars
Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au
It has a bright yellow colour and lustre traditionally considered attractive, which it maintains without oxidizing in air or water. We export gold in nuggets, grains, scrap or dust form Au from 80 – 92 %

Ingot Bullion
We provide investment bars 99.9% assayed, title holder certificate and refinery seal; secure transportation up to 500kg provided contact us.

 

Iron Ore
We extract Iron ore as economically possible for creation of steel. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red.
The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3).

 

Wolframite
Wolframite, iron manganese tungstate mineral that is the intermediate between ferberite (Fe2+ rich) and huebernite (Mn2+ rich). Dark gray, reddish brown, brownish black, or iron black in colour. Streak is dark red brown or black.


Utilized for glass-to-metal seals, amour piercing machinery. The tungsten or its alloys are used for filaments for electric lamps, electron and television tubes, electrical contact points for automobile distributors, heating elements for electrical furnaces, and space, missile, and high-temperature applications.

 

Columbite
Columbite, which is very close to Tantalite in crystalline structure in fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite. We provide Columbite just on its own if required

 

Ilmenite
Ilmenite is a weakly magnetic titanium-iron oxide mineral which is iron-black or steel-gray. It is a crystalline iron titanium oxide (FeTiO3). Our mining and processing of ilmenite is mostly for titanium dioxide production. When finely ground the titanium dioxide is a bright white powder utilized by our clients as a base pigment in paint, paper and plastics.

 

Manganese
Manganese provided for steel production, Aluminium alloys etc. in ore form

 

Green Beryl
Green beryl is a mineral composed of beryllium aluminium cyclosilicate with the chemical chemical formula Be3Al2 (SiO3)6.


The hexagonal crystals of beryl may be very small or range to several meters in size. We are able to source pure beryl which is colourless, but it is frequently tinted by impurities; possible colours are green, blue, yellow, red, and white.

Our beryllium is Utilized as jewellery and other adornments we cut, facet , and heat treat the beryllium then certify and export to our clients in Antwerp and other places contact for more details.

 

Thorium
Thorium is a naturally occurring radioactive chemical element with the symbol Th and atomic number 90.
CM Ltd provides thorium as a substitute nuclear fuel in nuclear reactors and alloying element in non-consumable welding electrodes.

 

Uranium
Uranium is a silvery-white metallic chemical element in the actinide series of the periodic table, with symbol U and atomic number 92. Uranium is weakly radioactive because all its isotopes are unstable.
Our clients major application of uranium is in the military sector this consist of high-density penetrators and ammunition which consists of depleted uranium (DU) alloyed with 1–2% other elements.

 

Silica
Silicon dioxide, we export Silica for production of glass for windows, drinking glasses, beverage bottles, and many other uses.

 

Cobalt
Processed to Lithium cobalt oxide (LiCoO2) which is widely used in lithium ion battery cathodes.
The material is composed of cobalt oxide layers in which the lithium is intercalated. Our cobalt improves the oxidation capabilities of nickel in the battery.
