(c) What in addition to a zinc compound, is put into the furnace? State one large scale use of zinc. Q. Name the metal which is extracted from the ore called 'Rock salt'. (b) Name two ores of zinc.
Due to its physical and chemical properties, notably ductility and malleability, aluminum is the most used metal after iron and steel (Geoscience Australia, 2018). Red mud is produced at a rate of 1–1.5 kg per kg of produced alumina (Al 2 O 3 ) ( Yang and Xiao, 2008 ), resulting in a world stock of ~4 × 10 12 kg in 2015 ( Gore, 2015 ; Mukiza et al., 2019 ).

In order to obtain one tone of aluminium, the following inputs are required: 4 tones of bauxite, 150 Kg of sodium hydroxide and 600 Kg of graphite. The aluminium compound in bauxite is aluminium oxide and the main impurity is iron (II) oxide.
As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. TiCl4 + 4Na → Ti + 4NaCl T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na+ + 4e− 4 N a → 4 N a + + 4 e −. These electrons are used to reduce
