Zinc Essential Chemical Industry

The thermal process. Under the conditions in the furnace zinc is a vapour (gas), whereas lead is produced as a liquid by a similar series of reactions. The other components of sinter such as silica (SiO 2 ), lime (CaO), alumina (Al 2 O 3) and iron oxide (Fe 2 O 3 /FeO), form a molten slag of silicates.

Nickel Products

Nickel is the main focus of our business in Canada, and Vale is the world's second-largest producer of this important metal. Nickel is rarely used in its pure form. Instead, it is combined with other metals, especially iron, chromium and copper, to produce alloys that are superior to the individual metals.

Coke Production for Blast Furnace Ironmaking

By-product Coke Production The blended coal is charged into a number of slot type ovens wherein each oven shares a common heating flue with the adjacent oven. Coal is carbonized in a reducing atmosphere and the off-gas is collected and sent to the by-product plant where various by-products are recovered. Hence, this process is called by-product cokemaking.

Cash cost Mining Moneyterms investment, finance and

The value of the by-products is deducted from the final cash cost of the metal. For example, if a copper mine produces gold as a by-product, then the value of the gold produced will be deducted from the cash cost of the copper. This is the usual accounting treatment for by-products in most industries.
