In Chile, the port of Mejillones has established high standards for the loading of zinc and lead concentrates. Safety systems are in place covering the reception of sealed containers and the storage of consignments in warehouses equipped with dust suppression systems. Transport to the quayside is via a tubular conveyor network, which prevents any contamination of the environment from the concentrates.
In addition, the port is relatively separated from the local community, located on the local industrial estate, which also ensures that contamination can be easily controlled.
Such has been the success of the handling of concentrates, that the port is now seeking to handle other mineral concentrates, too.
