At the beginning iron was inferior to copper, because it was very brittle. Depending onposition of the iron ore and the manufacturing process used, the iron produced in a so called bloomery can have either a lower or higher carbon content. By controlling the temperature and ratio of charcoal to iron ore carefully, the iron is kept from

25/06/2001· The monument includes two mines, a spoil heap and an ore dressing floor which formed part of Dale Head copper mines. It is located high on the fellside amongst Dale Head Crags above the Newlands Valley 300m north east of the summit of Dale Head.
The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wetted, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic. Typical reagents include potassium ethylxanthate and sodium ethylxanthate, but
Many copper ore deposits, such as the sulfide ores, do have an arsenic ore content. It is possible that the early metallurgists found that adding arsenic ore to their cop per gave the desired effect, but so far there does not appear to be any evidence that this was intentional. continued on page 2 oi.uchicago.edu.

Simple ore dressing devices had been developed by the 16th century, but the large majority date from the 18th to 20th centuries, when technology evolved rapidly. During English Heritage's national evaluation of the copper industry, 130 sites were assessed.
Ancientg barrels would have been made of copper, either cast or cold worked until the Middle Kingdom, when bronze tools became more readily available. Some ancient core holes still contain weathered copper or bronze residue and rock tailings/abrasive Lucas and Harris 1962, Stocks 1986. The ancient Egyptians began to make tools of smelted copper by cold working and casting
The use of tin as a coating for other metals also has ancient historical roots, with tinned copper vessels for cooking tracing back to Roman times. Most important was the development of tinning iron sheet in order to form tinplate. This began in central Europe in the 14th and 15th centuries and gradually spread throughout the continent.
Ancient copper mines such as the ancient copper mine in Tongling, have been discovered. Wooden chutes dating back to the Zhou dynasty have been found at this mine. These chutes were used for ore dressing. Ore dressing is when the things found inside the mine are separated out. There are two methods of ore dressing, and they are crushing and

Themon compound is the copper carbonate malachite. It was often grounded up to use as a green paint and regarded as the best source of metallic copper. Another kind of copper carbonate, which gave the blue colour, is called azurite. Besides, there are two forms of copper oxidecuprite and melacouite and many sulpides of copper.
In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs ofs under which further belts ran at right angles to the feed belt. The first pair ofs was weaklyised and served to draw off any iron ore present. The second pair were stronglyised and attracted the wolframite, which is weaklyic. These
