Реферат

Data on development of roasting process of fine-dispersing zinc concentrates in fluid-bed furnace of the Chelyabinsk Zinc Plant is presented. Influence of both chemical and physical properties of a concentrate on roasting process is shown. Recommendations on preparation of a concentrate to roasting are given. Design features of furnaces and their influence on stability of work of fluid-bed furnace are considered. Influence of a condition of boiling bed of the furnace on technological modes of roasting is defined. Directions of improvement of roasting process are formulated.

Ключевые слова Zinc concentrate, furnace-charge, roasting, fluid-bed furnace (FB furnace), temperature, granulometric structure, calcine.
