Abstract

For the efficient optimization of a multistage depressed collector (MDC), an axis-adjustable MDC optimized using the genetic algorithm (GA) is presented in this article. The optimization processes are realized with a reasonable balance between the collector recovery efficiency and electron reflux rate by modifying the fitness function of GA. Through the proposed method, the best recovery efficienc...
