Abstract: The quality improvement & impurity reduction of iron concentrate can bring a considerable economic benefit to both sintering and iron making. However, the price addition of the iron concentrate for quality improvement & impurity reduction by way of beneficiation calculated according to the present commonly used method is insufficient and can not reflect the true value of quality improvement & impurity reduction. Therefore, a cost recovery method for calculating the economic benefit of the quality improvement & impurity reduction of iron concentrate by way of beneficiation is proposed. Based on the batch calculation for sintering and iron-making, it calculates the economical benefit by taking mineral processing, sintering and iron-making as a whole so as to objectively reflect the economic value of the iron concentrate that is upgraded by quality improvement & impurity reduction in way of beneficiation. It is of reference significance to the rational pricing of the iron concentrate based on quality.
