In terms of price, lead-zinc mine should be no different from copper mine. Estimates are still based on LME futures. If it is only imported for domestic sales. The price calculation should be: CIF= lead and zinc content percentage XLME futures price (or price in a certain period) x recovery rate (or payment coefficient)+freight+customs clearance fee (abroad)+other miscellaneous fees.
To the domestic price, value-added tax and port operation fees need to be added.
In this way, you can get the cost of your mining. Referring to the domestic market price, the intermediate price difference is profit.
