· According to Morrison, "the essence of reconciliation is to track products back to source with as much knowledge as possible about how well the various components of that path are known".Proactive reconciliation was developed for detecting the causes of reconciliation problems at each process stage and can be used as a tool for integrating mining and milling operations in an .
So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size. The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill. Generally, rod mills operate between 280 feet per minute and 480 feet per minute at the periphery of the mill.

· The operation had two components: the mines where ore was extracted from the mountains, and the mill town where the ore was processed. From 1911 to 1938, nearly 200 million worth of copper was processed. At the peak of operation, approximately 300 people worked in the mill town and 200300 in the mines.
· 4577. HSS tool bits actually work very well when machining copper. Trick is to have a large swooping radius on the top face of the tool ( like this > ) but rotated 90°) and a steep cutting angle of 20° or higher. After grinding, hone the cutting edges sharp with an India stone.
capital cost and operating cost estimate for a 500,000t/year conventional CIL plant and a ... 132 kW stirred bead mill to further liberate the copper minerals. The regrind mill product will be directed to the copper recleaners for a f inal stage of cleaning.
· Advantages of Ball Mills. 1. It produces very fine powder (particle size less than or equal to 10 microns). 2. It is suitable for milling toxic materials since it can be used in a completely enclosed form. 3. Has a wide appliion. 4. It can be used for continuous operation.
Rolling Mills . In metal forming industry, rolls themselves do not function in isolation. In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill.
· GATE2008 (PI) In an electro chemical machining (ECM) operation, a square hole of dimensions 5 mm x 5 mm is drilled in a block of copper. The current used is 5000 A. Atomic weight of cupper is 63 and valency of dissolution is 1. Faraday's constant is 96500 coulomb.

· The cutting fluid recommended for machining steel with high speed cutting tools depends largely on the severity of the operation. For ordinary turning, boring, drilling, and milling on medium and low strength steels, use a soluble oil having a consistency of 1 part oil to 10 to 20 parts water.
· Executives felt that promising opportunities to boost Bagdad's production could be found in one part of the operation: the oreconcentrating mill, a noisy facility where huge milling machines and flotation cells bubbling with chemical solutions turn grapefruitsize rocks containing around percent copper into a fineground mix of 25 percent copper and 75 percent rock.
