Bauxite
​
Bauxite is a soft and light sedimentary rock that has a wide range of use thanks to its properties of easy workability, cold and hot workability, electrical and thermal conductivity, and corrosion resistance. Bauxite also has a relatively high aluminium content and is hence the world's main source of aluminium and gallium. Bauxite ore is mined, processed and then refined to recover alumina which in turn is smelted to produce Aluminium.
Beryllium
​
Beryllium is a grey metal element that is stronger than steel and lighter than aluminium. Its physical properties of great strength-to-weight, high melting point, excellent thermal stability and conductivity, reflectivity and transparency to X-rays make it an essential material in the aerospace, telecommunications, information technology, defence, medical and nuclear industries.
Chromite
Chrome ore lumpy consists of large lump formations, typically between 10mm to 300mm in size. This type of ore is mined directly from the earth and requires minimal processing before being sold. It is primarily used in the metallurgical industry to produce ferrochrome, an essential component in stainless steel production.
Nickel
​
Nickel is a metallic element with a silvery-white, shiny appearance. It is the fifth-most common element on earth and occurs extensively in the earth’s crust and core. Nickel, along with iron, is also a common element in meteorites. Nickel occurs naturally in soil and water. It is also an essential nutrient for plants. Nickel has many applications, including in batteries, alloys and consumer products.
Iron Ore
​
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are heated in the presence of a reductant to yield metallic iron. The ore almost always consists of iron oxides, the primary forms of which are Magnetite and Hematite. Iron ore is the source of primary iron for the world's iron and steel industries.
Tantalite
​
Tantalite is a mineral that serves as a source for Tantalum and occurs in the mineral columbite-tantalite (Coltan). Depending on the predominance of tantalum or niobium, the mineral is called tantalite or columbite. Tantalite is the main ore that contains Tantalum which is a very rare, corrosion-resistant metal widely used in electronics and chemical equipment.
