Detecting Slag Buildup on Ferrite Casings in Pipe Mills

A major challenge in producing good-quality pipe on a welded pipe mill is the buildup of slag on the ferrite bundle used inside the pipe. Slag is a mixture of metal oxides and silicon dioxide, which are byproducts of separating the steel from its raw ore. Ferrite bundles typically are placed inside the pipe to help concentrate the electrical

In addition, domestic secondary production from lead scrap totaled 880,000 mt in 1993, up from 842,000 mt in 1989. United States lead reserves totaled

Copper Recovery Through Smelter Slag Flotation in Atacama,

However, CS milling must be carried out in a very controlled way, as the excess of fine particles can lead to clogging of the piping and pumping systems. Some sulfides (bright grey) are closely associated and enclosed within larger slag particles (dark grey), which results in the unavoidable transport of slag to the concentrate.

After the concentrate is unloaded at what is called the sinter plant, it is mixed with other lead-bearing materials and with sand and limestone. Then the mixture is spread on a moving grate. Air which has been heated to 2,550F (1,400C) blows through the grate. Coke is added as fuel, and the sulfur in the ore concentrate combusts to sulfur dioxide gas. This sulfur dioxide is an
