density estimation (NKDE) function respectively to set the penalty weight. Comparison experiments are first carried out based on the UCI standard data sets to verify the effectiveness of these methods, and then the data-driven PS model based on the robust algorithms are established and verified. Experimental results show that the RSCN has an excellent performance for the PS estimation. Key words......
herein a highly selective method for directly determining the trace Co2+ in highly concentrated zinc electrolyte. This novel method is based on a second derivative wave of catalytic adsorptive... allowed concentration in the zinc electrolyte is 0.3 mg/L [2]. The Co2+ removal methods involved in various hydrometallurgical plants are based on zinc powder replacement and chemical precipitation......

Copy numbers of each conserved gene were quantified based... against the adverse bioleaching conditions such as possibly infertile bulk-solution composition and dynamic force (e.g., solution flows and abrasion) [34]. Moreover, the bioleaching bacteria existed......
