Copper Ores

Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Today, copper’s uses have expanded to include heating, cooling and refrigeration, electrical wiring, electronics, power generation and transmission, automotive applications, antimicrobial uses and many more.

Types of Copper Ores

Chalcocite

Chalcopyrite

Bornite

Malachite

Azurite

Chrysocolla

We provide all kinds of copper ore for the industry.

Lead Ore

The lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids (typically between 50 and 150° C) rising up from depth and depositing various minerals as they cooled. The source of the fluids were the deep sedimentary basins either side of the Mendips. As the Triassic and Jurassic sediments in these basins were buried, compacted and heated over time, some of the water in the rock was forced out, along with any dissolved metals and migrated into the neighbouring Carboniferous Limestone. Here the change in chemistry, temperature and pressure led to the deposition of various minerals including lead, zinc, and locally copper.

Types of lead ore

Lead ore is most commonly found as lead sulphide (PbS), galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate (Pb₅(PO₄)₃Cl), was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver.

Lead Sulphide

Galena

Pyromorphite

Lead Chlorophosphate

The lead ore occurs in two types of deposit: as primary lead ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary lead veins.

We can provide all kinds of lead ores to match our customers needs.
