materials used in steelmaking are iron ore, coal, and limestone. These materials are converted in a blast furnace into a product known as "pig iron," which contains considerable amounts of carbon (above %), manganese, sulfur, phosphorus, and silicon. Pig iron is hard, brittle, and unsuitable for direct processing into wrought forms.

Answers to Questions in Unit 1 6 Answers to Questions To Master Worksheet 1. Natural Resources — the land itself where the factory is located; wood; iron; water and air used in production; energy sources, such as coal, oil, or natural gas. Human Resources — workers who cut trees or mine iron ore, workers on the assembly
Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and
