Pure HF boils at 19 degrees Celsius and this relatively high boiling point is used to purify the gaseous mixture by distillation. Theoretically, tons of pure CaF2 will yield one ton of HF, but impurities in the fluorite ore and the sulfuric acid generally require that greater tonnages of both be used in the reactors.

Introduction to Iron and Steel A few definitions and general descriptions are in order Pig iron: Raw iron, the immediate product of smelting iron ore with coke and limestone in a blast furnace. Pig iron has a very high carbon content, typically 45%, which makes it very brittle and not very useful directly as a material. A Selection of Mechanical

EXTRACTION OF TITANIUM. Recently it has been found that titanium dioxide, when spiked with nitrogen ions, or doped with metal oxide like tungsten trioxide, is also a photocatalyst under visible and UV light. It is also used in the Graetzel cell, a type of chemical solar cell.

of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce % pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation

introduction. Iron ore pellets are used for the production of hot metal in blast furnaces and DRI/HBI in direct reduction processes. A blast furnace is a shaft furnace, which is charged with iron bearing materials (pellets, sinters and/or lump ore), reducing agents (metallurgical coke) and additives (limestone, quartz, BOF slag).

The TaylorMedley store was a center of the community. Residents bought goods, picked up mail and got married at the store. It operated until the 1950s.

furnace, ore is heated in the presence of carbon—this allows oxygen in the ore to react with carbon to form gases. Limestone—helps to remove impurities Iron ore—processed ore at the start of the process has about 65% iron. Impurities (slag) float on the top of melt. Requires about tons of raw materials to produce ton of steel. 22

Ore:a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue:the valueless mineral particles within an ore deposit that must be discarded. Waste:the material associated with an ore deposit that must be mined to get at the ore and must then be discarded. Gangue is a .
