companies that process nickel slag
After leaching the nickel out of the nickel speiss and turning it into nickel sulfate, the remaining precious metals residue is treated at the precious metals refinery. The copper matte is returned to the smelter. The depleted blast furnace slag is physically calibrated for use in the concrete industry or used as dyke fortification substance.

Ore and base metals are weighed in Avoirdupois long or short tons or in metric tons. 1 metric ton = 1000 kilograms. 1 long ton = 2240 pounds. 1 short ton = 2000 pounds. Precious metals are weighed by metric or troy weights. The common weights in the metric system are the following: 1 metric ton = 1000 kilograms (kgs.) 1 kilogram = 1000 grams (g.)

The LeRoi Smelter and the Upper Columbia River Basin
To extract the precious metals, entrapped and oxidized in its rock encasings, the ore was blasted in a furnace with chemical agents. The pure metal, freed and melted, oozed out of the furnace and cooled, becoming a valuable lump of refined metal, while the ore's impurities and leftover chemicals, called slag, were collected and disposed of.
