ROASTING FURNACE, USE THEREOF AND METHOD FOR THE PROCESSING OF ORES OR CONCENTRATES.

摘要

The present invention provides a roasting furnace for processing ores or concentrates, preferably molybdenum-containing ores or concentrates, wherein 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 object of the invention is to provide a roasting furnace of said type with improved processing capacity and/or a reduction in the number of halts, and consequently to be more energy-efficient, more environmentally-friendly and more economically interesting.
