Abstract:With the continuous development of laterite nickel ore, the use of high-pressure acid leaching green and low-cost technology for low-grade nickel ore is gradually being promoted on a large scale. However, how to achieve high production and low consumption control is a prerequisite for high operating rate of key equipment. In the high-pressure leaching of hydrometallurgy, the service life of the flow components of the key equipment high-pressure reactor diaphragm pump is an important factor that directly affects production capacity and cost. This article introduces the current technology in equipment design, operation, maintenance, and improvement, and compares the lifespan of overcurrent components under different working conditions and materials. It provides important reference significance for equipment selection, maintenance, and improvement in subsequent laterite nickel mining projects.
