Abstract:

The bedding and blending process of iron ores has been investigated by means of laboratory trials, industrial sampling and a mathematical model. It has been revealed in the present work that an increase in the total number of ore ingredients participating in the proportioning procedure would greatly improve the quality of the base mix. The appropriate number of starting points of the stacker that simultaneously meets the demand on decreasing the amount of recirculating materials from the stockpile head and on easing the operation of the stacker can be determined with the proposed model. The technology of the ore bedding and blending process has been optimised based on the present research and the performance of the bedding and blending plant has been greatly improved.
