The concentrate mixture is fed into our sinter plant then a blast furnace heats the concentrate to 1 450 degrees Celsius This process melts the concentrate into liquid separating and drawing out impurities leaving only crude lead.

A by product of our mining and processing operations silver is extracted from our lead bullion blocks after export to our Britannia Refined Metals Facility in England for further refining.
6 1 Process Overview 6 1 1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations though a few surface operations do exist.
Only about 5 of the worldx0027s zinc supply is mined in the United States with the balance coming primarily from India Mexico and Canada Approximately 6 7 million metric tons of zinc ore are produced worldwide Roughly two thirds of the zinc used in the United States is imported.
In an application similar to the sacrificial anode zinc is used as a component in battery production The dry cell battery creates a chemical reaction with zinc in a metal housing or x0022canx0022 that results in a voltage potential between two connections An electrical device such as a flashlight or portable radio can be connected to the battery and powered by the electricity produced Thus connected the reaction maintains the electrical current for the duration of the available chemical reactants.

Because of the strength to weight ratio of zinc its use by the automotive industry as a die casting has been diminishing in the past few years Magnesium aluminum and plastics have taken over many zinc applications The use of zinc to galvanize automobile body parts has been increasing however Many vehicles today are protected by zinc galvanizing which allows the manufacturer to offer extended warranties for body rust problems with new cars.

We mine and process zinc and lead ores in the key mining regions of Australia South America Kazakhstan and Canada And we smelt and refine zinc and lead at processing operations in Australia Canada Spain Italy Germany the UK and Kazakhstan We also source and recycle zinc and lead materials in Europe and North America.
Nov 19 2019nbsp018332Zinc mining and process instrumentation Ore to industry To combat potential production issues the need for high quality efficient equipment is critical Like many other Australian mining operations zinc mines are underground and heavily rely on mechanisation and technology for efficient functioning.
Zinc is primarily produced by mining but can be recycled There are several ores from which zinc can be extracted zinc silicate calamine franklinite manganese zinc carbonate smithsonite.
