Abstract
A roasting furnace for processing ores or concentrates, preferably molybdenum-containing ores or concentrates is described. The roasting furnace contains at least one first rotary lifting system for the displacement of said arm along the axis direction, wherein said first rotary lifting system is a telescopic lifting system, and/or wherein a distance x between two consecutive said stages of said roasting furnace are at least 1.000 m, wherein said distance x is measured along the axis direction. The roasting furnace of has an improved processing capacity and/or a reduction in the number of halts, and consequently is more energy-efficient, more environmentally-friendly and more economically interesting.
