THE STORY OF THE MIAMI

The Miami Copper Company's property has been an underground 'minirig operation with a block-caving system of mining to take out the ore When the 6,000 ton mill was ready to start in 1911, gravity concentration was standard practice, and the mill was equipped with chilean mills for fine-crushing, and tables for concentration...

How copper is made

Most of the copper ores mined in the United States contain only about 12-16% copper by weight The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore Chalcocite, Cu 2 S, is another sulfide ore Cuprite, or red copper ore, Cu 2 O, is an oxide ore...

First Quantum Minerals Ltd

Sulphide ore is treated in the flotation plant producing a copper-gold concentrate The tails from flotation are treated in the magnetite plant to produce a high-quality, low-cost iron concentrate The plant currently produces approximately 15,000 tonnes of concentrate per month at a grade of 225% copper with credits received for the gold in ....

Bond Work Index

The Bond work index is not solely a material constant but is influenced by the grinding conditions For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size Magdalinovic [38] measured the Bond work index of three ore types using different test screen siz He produced a correlation between the mass of test screen undersize per revolution, G, and ....

Copper Concentrates

For special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper, this mineral can be recovered by a simple gravity circuit Application Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide...

Britannia Mines Concentrator

Copper was first mined in the area in 1903 and the distance from smelters necessitated the construction of an ore concentrator, a system to deliver ore, and a system to ship the ore concentrate A primitive concentrator, No 1, was built in 1904, which was upgraded with two more units, collective known as No2, built in 1914 and 1915...

Metal Production from Concentrates

Aurubis imports most of the copper concentrates directly from copper mines in different countri Copper ore is primarily mined in Central and South America, the US and Canada, as well as Africa, Asia, Australia and to a lesser degree in Europe Copper ores contain about 05-4 % copper and are already processed into a concentrate in the mine...

Copper Ore Cars

Jan 06, 2011· While the book doesn't have any scale plans on the hopper cars, there are some photos that show relatively low-side 2-bay steel hopper cars They are definately hopper cars and not the "shorty" ore cars They appear to be about 36' long The lower sides makes sense, though, as the copper ore/concentrate is likely denser or heavier than coal ....

Bond Work Index

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 336 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi) The work index calculations across a narrow size range are conducted using the appropriate laboratory work ....
