On this site you will find companies that manufacture, cut, shape, carve, polish and give a face lift to all different types of gemstones in Zambia. Check this section for further information on where to find these companies. A lapidary is an artist or artisan who forms stone, minerals, or gemstones into decorative items such as cabochons, engraved gems, including cameos, and faceted designs. The primary techniques employed are cutting, grinding, and polishing. There are surprising diversity of gemstones in Zambia; emeralds, rubies, beryl, coral, garnet, feldspar, opal, quartz, sapphire, ruby, topaz, tourmaline and turquoise.

Gemstones and Lapidary

Find details of companies that provide metal refinery services in Zambia. On this site you will find companies that manufacture and refine metal products, silver, gold, platinum and copper to suit different customer needs and wants. Check this section for further information on where to find these companies. Zambia is one of the world’s largest producers of copper. After mining the copper ore is crushed in a concentrator, and then melted in a smelter having been mixed with limestone. The copper is the cast into anode by electrolysis in a refinery. Find a fully-integrated precious metals company that acquires, refines and mints precious metal bullion products for clients. 

Metal refineries

Mining of copper, cobalt, emeralds and other minerals and semi-precious stones is a major industry in Zambia. Specialist mining chemicals are needed for solvent extraction and other processes. Companies can supply these chemicals to mining enterprises operating in Zambia.

Mining chemicals

There are many mining enterprises in Zambia that operate mines ranging from small scale enterprise to global conglomerates operating in Zambia from South Africa, Australia, India, China, the UK and USA. These mining enterprises mine copper, gold, platinum, coal, silver, nickel, tin, iron ore, limestone and gemstones. This category lists the companies engage in this activity including industrial mineral exploration and processing of the material. Chinese firms are involved in mining enterprises in Zambia and are becoming one of the biggest players in this sector. Copperbelt Province is the traditional epicentre of Zambia’s mining sector but the North Western Province is now the central player in this sector development.

Mining processing and refining

Mining production involves the extraction of minerals and other geological materials which are transformed into a mineralised form that serves an economic benefit to the prospector or miner. Machinery, equipment and processes are used all over the world to mine and process raw materials. This is to make the production and processing of raw materials as efficient and sustainable as possible.Over the years, mining production has evolved from being manual, unsafe, dirty and small-scale to being partially- or fully-automated, safer, cleaner and large-scale. Unlike their predecessors, today’s miners are highly trained personnel performing skilled work in accordance with the highest health, safety and environmental standards.ProcessingThe method used to separate the mineral or metal materials from the ore depends on the type of minerals or the grade. The first part of the process is to reduce the size of the pieces of mined material. It might be crushed into pebble-sized pieces or ground into a fine powder.The mineral or metal is then extracted by one of the following processes, or by a combination of them:<ul><li>Gravity</li><li>Using heavy oils</li><li>Mechanically with cyclones</li><li>Chemically with water and reagents (sulphuric acid or cyanide).</li><li>Mechano-chemically in flotation vessels</li></ul>After extraction, the mineral or metal product (in solid, slurry or dissolved form) may require further processing to increase its purity.The waste is sent to long-term storage. Coarse waste is moved to a residue pad and tailings (fine waste) is pumped to the tailings storage facilityPurificationThe state (solid, liquid or dissolved) of the mineral or metal will determine the type of purification method to be used. Some products, like iron ore, only need to be sized and shaped. To produce London Metal Exchange (LME) grade copper cathodes the copper must first be changed from a dissolved to a solid state by solvent extraction or activated carbon adsorption. This is then followed by electrowinning and electrorefining.

Find businesses in the Zambian mining sector specifically involved in the removal of minerals from out of the earth and their refining ready for market. These companies include mining enterprises, metal refineries and gemstone and lapidary businesses. Some of these companies mine and refine copper, with cobalt as a by product. Others extract, shape, cut, carve, polish and set the different gemstones found in Zambia, such as emeralds and amethysts.
