Metals & Mineral resources
BAUXITE
We are suppliers of bauxite from Guinea, Ghana, Mozambique & other African countries. Bauxite, known mostly as aluminium ore; is a naturally occurring, heterogeneous material composed primarily of one or more aluminium hydroxide minerals, including the trihydrate gibbsites, the monohydrate polymorphs boehmite and diaspore plus various mixtures of silica, hematite (iron oxides), siderite (iron carbonates) and other impurities in trace amounts. Most bauxite deposits contain rutile, anatase, zircon and other minerals. To produce refined aluminium metal which is used in various applications in transport, aerospace, building, construction and packaging among others, bauxite ore is processed into Alumina (aluminium (III) oxide). Bauxite is a natural mineral material occurring mostly in the tropical areas. Annual global production of bauxite is more than 370 million MT as of 2020. Alumina is an amphoteric oxide of aluminium with the chemical formula Al2O3. After bauxite is transformed into alumina, alumina is further processed and refined through an electrolytic process resulting into pure aluminium. The main varieties of bauxite include: Metallurgical grade bauxite; Refractory grade bauxite; Abrasive grade bauxite; and Chemical grade bauxite and can supply bauxite from Guinea, Ghana, Mozambique & Tanzania. in Africa to clients worldwide
COPPER
We supply copper cathodes from Zambia, Congo and South Africa. We deliver copper directly to reputable global refiners, smelters, fabricators and manufacturers of copper components around the world who transform these raw materials into important copper products that impact on daily lives of consumers worldwide. We currently originate copper from Zambia, Democratic Republic of Congo and we are also extending our origination to Botswana and South Africa. We offer worldwide supply of copper cathodes grade A with 99.7% to 99.99% purity free from all foreign materials such as copper sulphate, dirt, grease and oil.
CHROME
We supply bulk chrome ore and chrome concentrates from South Africa, Zimbabwe and Zambia. Chrome ore is an important mineral for production of chromium which is principally used as an alloying ingredient in stainless steel. NARGIS Group is firmly committed to establish long term supply relationship with clients from around the world through which we hope to support these partners with reliable supply solution for quality chrome ore and chrome concentrates. We have special interest in creating value for our partners and clients. We have the necessary logistics partners to move these products efficiently from the origin in South Africa, Zimbabwe or Zambia to customers’ destination within time frames acceptable. We similarly focus to pass cost savings associated with economies of scale directly to our esteemed clients. Specifications and Purity of Chrome Our goal is to be best suppliers of chrome ore and chrome concentrates in term of consistency of value created for our clients and partners. We supply chrome ore and chrome concentrates in lumps and fines, offering three major grades: Cr2O3: 40% – 45% Cr2O3: 45% -50% Cr2O3: 50% – 50%
COBALT
Cobalt is one of the three naturally occurring magnetic metals in addition to iron and nickel. Cobalt has the highest curie point of all metals at 1,121 oC (the temperature above which a ferromagnetic material loses its ferromagnetism). Our supply of cobalt is concentrated on sourcing primarily from the Democratic Republic of Congo, Zambia, South Africa and Zimbabwe. The main source of cobalt accounting for approximately 85% of annual production globally, is as a byproduct of nickel mining (about 48%) and copper mining (about 37%). Some 15% of cobalt is produced primarily from various metallic-lustered ores, for example cobaltite, erythrite and skutterudite. Cobalt is predominantly used in the preparation of magnetic, corrosion and wear-resistant high performance alloys. We focus on clients from diverse industries including alloys, battery manufacturers, manufacturers of cobalt acetate and other cobalt compounds used as catalysts in chemical reactions, radioisotopes and electroplating among others
IRON ORE
Iron is the second most abundant metal in the earth’s crust (after aluminium). The iron ores, which are mainly the oxides, are reduced to iron with carbon (coke) at high temperatures in a blast furnace. Over 97% of this is converted directly to steel without even being allowed to solidify after leaving the furnace in which it is made. A relatively small amount is used as cast iron and wrought iron. Iron ore is a key commodity and vital product portfolio for NARGIS Group. As rapidly growing suppliers of iron ore from South Africa, our approach is to lift the ore from where it is produced in South Africa and deliver it directly to industrial end users or trading houses in Asia and Europe where it is demanded. Our offer for iron ore is priced off the main price indices. NARGIS Group is also able to supply niche products such as the iron ore pellets and fines for foundries, iron additives and ferroalloys. NARGIS Group has reliable long term access with its partner and can assure steadfast supply of 64.5% Fe Base, 62% Fe Base, 58.3% Fe Base and 58.0 % Fe Base grades of iron ore. However the Fe% of every shipment may vary. If the iron ore shipped is at a higher or lower percentage than the Fe % Contracted Base, then the price paid for the shipment will escalate or reduce in accordance to the percentage of Fe in the ore that is actually supplied.
LITHIUM ORE
Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite LiAl(Si2O5)2, lepidolite K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2, spodumene LiAl(SiO3)2 and also subsurface brines. Lithium compounds are used in ceramics and glass, in primary aluminum production, in the manufacture of lubricants and greases, rocket propellants, vitamin A synthesis, silver solders, underwater buoyancy devices, and increasingly in batteries. Lithium batteries are proving to be an effective and affordable alternative to traditional batteries, and also used in new battery applications. More than 80% of lithium mined is used in batteries. This use has recently increased rapidly spurring an increase in lithium mining to provide the lithium for batteries. Lithium is mixed with other light metals such as aluminum and magnesium to form strong, light-weight alloys (an alloy is a mixture of metals). Some lithium, in the form of lithium carbonate or lithium citrate, is used as medicine to treat gout (an inflammation of joints) and to treat serious mental illness.
