Lithium is known as the energy of metal and metal push the world forward. Lithium brine system, often with trace components and sodium, potassium, magnesium, calcium and so on coexist, and different water quality conditions, the existence of the lithium is different also, ion exchange adsorption method with its simple process, high recovery rate, as well as good selectivity to stand out. Resin technology co., LTD. Suzhou bo jie of extracting lithium resin for lithium adsorption rate is high, fast adsorption and desorption easy, can be selectively extracting lithium, operation process is relatively simple, good mechanical strength, renewable and recycled, regeneration utilization high, soluble loss rate is low, the efficiency of extracting lithium project, and reduce the corresponding cost, increase the enterprise economic benefit of extracting lithium.
