Boliden /Kaldo process

Boliden (2) A lead extraction process in which a sulfide ore, mixed with coke, is smelted in an electric furnace, air jets forming vortices between the electrodes. Discontinued in 1988 in favor of the Kaldo process, using a rotating furnace.

The TBRC is represented by the Kaldo process, developed and operated by Boliden in Sweden and detailed in Chapter 7. This process is suitable for both primary and secondary smelting and can accept whole batteries if required. The Kaldo system at the Ronnskar smelter has adequate facilities for the capture of sulfur and paste desulfurisation is unnecessary.

Boliden opened a plant using this technology in Sweden in 1976, the first direct smelting process to be used for the commercial production of lead in the Western World. The Kaldo furnace (or top blown rotary converter), is in widespread use for nickel and copper smelting and refining, but Boliden s 65000tpy Ronnskar plant is the sole example in the lead industry.
