What Are the Three Stages of Production in Economics

In economics, the three stages of production are increasing average product production, decreasing marginal returns and negative marginal returns. These stages of production apply to shortterm production of goods, with the length of time spent within each stage varying depending on the type of company and product. Keep Learning.

How aluminium is produced All About Aluminium

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.

The Making of Iron Steel SEAISI

Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).

Steelmaking

Steelmaking

The puddling furnace was initially a means of producing wrought iron but was later applied to steel production. The real revolution in modern steelmaking only began at the end of the 1850s when the Bessemer process became the first successful method of steelmaking in high quantity followeded by the openhearth furnace .

Iron processing. Mostly it appears in iron carbon alloys such as steels, which contain between 0.003 and about 2 percent carbon (the majority lying in the range of 0.01 to 1.2 percent), and cast irons with 2 to 4 percent carbon. At the carbon contents typical of steels, iron carbide (Fe 3 C), also known as cementite,
