In the development of hydrometallurgical processes, scaling up from laboratory research to industrial production is a critical step that often determines the success or failure of a project. The CWX-J Series laboratory mixer settler, independently developed by Zhengzhou Tiei Extraction, are specifically designed for the development of extraction and separation processes for metals such as copper, cobalt, nickel. They provide a complete solution from laboratory-scale testing to pilot-scale scale-up, ensuring accurate and reliable process data and a scientifically controlled, predictable scale-up process.
Equipment Design Principles and Process Adaptability
The CWX-J Series mixer settler adopts a classical mixing and clarification structure. By precisely controlling mixing intensity and clarification residence time, it achieves efficient mass transfer and complete phase separation between the metallurgical feed solution and the extractant system. For different metal extraction systems (such as the high selectivity requirements of copper extraction), the equipment can optimize the agitator blade design and clarification zone structure to ensure that experimental data accurately reflect industrial conditions.
Professional-Grade Laboratory Equipment Advantages
1. Precise and Reliable Experimental Data Output
Stable single-stage extraction efficiency maintained within the range of 85–98%, with high data reproducibility
Interstage flow-through design eliminates back-mixing, accurately simulating multistage countercurrent extraction processes
Transparent tank structure allows real-time observation of phase interfaces and mixing behavior
2.Flexible Process Adaptability
Five equipment sizes covering throughput capacities from 3.6 to 108 L/h, meeting the requirements of experiments at different scales
CWX-0.3J and CWX-1J mixer settlers are suitable for process screening and parameter optimization
CWX-6J and CWX-9J mixer settlers support continuous pilot-scale operation and scale-up validation
Multiple material options to accommodate various corrosive media (acrylic, PP, fluoropolymer materials)
Typical Application Cases
Case 1: Development of a High-Purity Cobalt Extraction Process
A new energy materials company utilized the CWX-2J mixer settlers unit to develop a cobalt–nickel separation process. Through 15 days of systematic experimentation, the optimal pH control range (4.2–4.8) was determined and the extractant formulation was optimized (22% P507 concentration). Based on these results, the industrial production line was commissioned successfully on the first start-up, achieving a cobalt purity of 99.95%.
Case 2: Pilot-Scale Treatment of Complex Copper-Bearing Solutions
A mining operation employed the CWX-9J mixer settlers unit for a 2,000-hour continuous pilot test to treat a complex solution containing 1.8 g/L copper and 12 g/L iron. The copper extraction rate was stably maintained above 98.2%, while iron co-extraction was controlled within 1.5%. The pilot results provided a reliable design basis for a hydrometallurgical copper project with a capacity of tens of thousands of tonnes.
The CWX-J Series laboratory mixer settlers developed by Zhengzhou Tiei Extraction have been successfully applied in more than one hundred metallurgical R&D projects. We are committed to providing the metallurgical industry with scientifically rigorous experimental program design, accurate and reliable experimental data support, professional and responsible technical consulting services, and a continuously improving after-sales support system.
