Smelters | Colorado Miners
The ore smelting business helped develop coal mining in Colorado. The smelters needed fuel for their blast furnaces. After cutting down the nearby forests for wood, the smelter owners began using coke. Coke is coal that is partly burned to remove impurities. The remaining coke burns much hotter than ordinary coal.

Limestone – Algyr
Limestone. Limestone (CaCo3) is a sedimentary rock of chemical or biochemical origin that is composed mostly of calcium carbonate. This rock is mostly found in the form of clay limestone, sandy lime and dolomite. Pure lime is white, but the presence of impurities can change its color to some extent. If the impurities of limestone are magnesium

How Does a Blast Furnace Work?
The raw materials for blast furnace smelting are mainly composed of iron ore, fuel (coke) and flux (limestone). Usually, smelting 1 ton of pig iron requires 1.5-2.0 tons of iron ore, 0.4-0.6 tons of coke, 0.2-0.4 tons of flux, and a total of 2-3 tons of raw materials.

Smelting and Selective Reduction of Limonitic Laterite Ore
Generally, NPI production through Blast Furnace has a recovery value of 80% [ 22, 28 ]. This study aims to study the smelting process of limonitic laterite ore using a MBF pilot plant with a capacity of ten tons of ore per day. This smelting process uses coal as fuel and uses flux in the form of limestone.

Types of Metal Melting Furnaces
The insides of these furnaces are lined with clay, blocks or bricks which protect the furnace''s interior from heat, abrasion and oxidation. To melt the metal in the furnace, workers add layers of metal such as ferro alloys, limestone and coke. The limestone reacts with the metal, making the impurities float up to the surface of the melting metal.

Iron Furnace
Water from the stream powered large bellows and a massive hammer mill. Each day 625 bushels of charcoal (approximately 52 trees), 6 1/4 tons of iron ore, and 1,563 punds of limestone were used to produce approximately 3 tons of iron. The furnace, which was known as Newlee''s Iron Furnace, operated throughout the 1800''s.

12.9 Secondary Copper Smelting
Smelting of low-grade copper scrap begins with melting in either a blast or a rotary furnace, resulting in slag and impure copper. If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved.
