Recovery of High Value Metals

Companies are increasingly looking for sustainable technologies for recovering strategic high value metals. Many of these metals are in tight supply due to rapid increases in demand associated with highly technical applications (electronics) and even the state of the economy (such as gold). The recovery of high value metals from industrial processes is well suited for Thermax specialty ion exchange resins. Thermax has a broad range of products that can meet the most demanding requirements that are often common to industrial processes. Thermax combines the efficiency of its resins with proprietary ion exchange equipment systems to provide the highest recovery rates with the lowest regeneration ratios. Recovery of metals from process streams reduces toxicity and provides a rich source of income for current operations. Use of Thermax technology combined with high market prices for metals may make it profitable to reprocess stored waste slag.
