ISO/TC 183. ISO. ISO 13543:2016 (Amendment) Copper, lead, zinc and nickel sulfide concentrates — Determination of mass of contained metal in a lot. ISO 13543:2016 specifies the method for determining the mass of contained metal in a lot, based on the wet mass, moisture content and dry basis metal content of the lot.

This document specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of cadmium in copper, lead and zinc sulfide concentrates as follows: a) for copper sulfide concentrates, the method is applicable to the determination of mass fractions of cadmium from 0,01 % to 0,30 %;

3. Flotation equipment. At present, the lead-zinc dressing plant uses 5A and 1A flotation machines. Due to the flotation machines' long history, equipment operation's high failure rate, and the poor separation index, we replace all the flotation machines with BF flotation machines. BF-2.8 flotation machines are used for priority flotation roughing …

11.55 million tonnes Lead and that of zinc is 36.66 million tonnes and for lead zinc metal is 118.45 thousand tonnes. In terms of reserves, 2.24 million tonnes of lead metal and 12.45 million tonnes of zinc metal have been estimated. Rajasthan is endowed with the largest resources of lead-zinc ore amounting to 607.53 million tonnes

A chemical agent called a depressant is added to a tank with the lead and zinc particles. This causes most of the zinc ore to sink to the bottom and the lead ore to float to the top. The lead ore then gets skimmed off. (Additional chemicals, such as copper sulfate, allow the zinc ores to be skimmed off later in the process.)
