Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

Water is primarily used in forestry and fishery, agricultural production (in its entire agri-food supply chain) and is used to create and/or transfer energy in varying forms. [ 6 ] In fact, agriculture is the largest user of freshwater, making it responsible for 70% of total global withdrawal, while more than one fourth of energy used worldwide ...
Laterite ores are often used to supply the production process. [13] [14] The RKEF process is often used. [15] The energy consumption per tonne of product is high for laterite ores because of the low-grade feed, and hence produces a lot of waste slag and gaseous pollution. [16] Generally, over 90% of the furnace output is in the form of slag. [8]
Iron metallurgy in Africa concerns the origin and development of ferrous metallurgy on the African continent.Whereas the development of iron metallurgy in North Africa and the Horn closely mirrors that of the Ancient Near East and Mediterranean region, the three-age system is ill-suited to Sub-Saharan Africa, where copper metallurgy generally does not precede iron working.

Aluminium in Africa originates from bauxite, and within Africa is primarily found in Guinea, Mozambique and Ghana. [1] Guinea is by far the biggest producer in Africa, and is a world leader in bauxite production. [2] There are many companies involved in the aluminium trade in Africa.
The second-largest mineral industry in the world is the mineral industry of Africa, which implies large quantities of resources due to Africa being the second largest continent, with 30.37 million square kilometres of land.With a population of 1.4 billion living there, mineral exploration and production constitute significant parts of their economies for many African countries and remain keys ...
Major sources of human oral exposure to aluminium include food (due to its use in food additives, food and beverage packaging, and cooking utensils), drinking water (due to its use in municipal water treatment), and aluminium-containing medications (particularly antacid/antiulcer and buffered aspirin formulations). [200]
The main sources of Africa's 3.6% share of the world's Carbon dioxide emissions are gas flaring in the Niger Delta and coal-fired power plants in South Africa. [23] But, the continent's forests are rapidly disappearing because of desertification and deforestation, which has negative consequences for both Africa and the climate at large. [24]
