Jun 26, 2018018332The total rare-earth oxide TREO content within a deposit is a strong indicator of its economic value. However, projects cannot be compared based on the proportion of TREO in the ore because HREEs command a much higher price than LREEs. Our company is a professional manufacturer of various crushing, sand making, grinding, mineral processing and building materials products. There are more discounts for consulting now.
