Copper, lead, zinc and nickel concentrates — Sampling
chemical analysis, physical testing and determination of moisture content, in accordance with the relevant International Standards Where the concentrates are susceptible to significant oxidation or decomposition, it is necessary to use a common sample for moisture determination and chemical analysis to eliminate bias (see ISO 10251)Concentrates are usually specific to particular smelters Thus a lead smelter or a zinc smelter could not smelt a copper concentrate (the converse is also true) In fact any copper in a lead or zinc concentrate is generally problematic in the smelting/refining processes and would most likely incur a penalty charge (see more on penalties below)Selling Metal Concentrates: Payable Metal, TreatmentProblem 1: Material balance in roasting of zinc concentrate Zinc concentrates of a location are composed of 60% zinc, present asZnS, iron present as Fe and On roasting Zn oxidizes to ZnO, iron to Fe and S to SO of ZnS however, remainsLecture 19: Roasting of zinc and lead concentrates 911 The need for analysing copper concentrates to determine the copper content accurately and rapidly is increasing All data from standards, sample replicates, individual reagent additions, and endpoint calculations are logged in the database with the sample replicate ID Automated cleaning routines enable reuse of titration flasksWhitepaper Automated analysis of copper concentrates
