gold cil carbon in leach process is an efficient design of extracting and recovering gold from its ore. by cyaniding and carbon leaching crushed gold ore slurry simultaneously, cil process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
processing industries are mostly of the tumbling mill type. these mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. the grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. this motion can be characterized as collision with breakage
during gold ball wire bonding, a gold ball is first formed by melting the end of the wire which is held by a bonding tool known as a capillary through electronic flame-off efo . this free-air ball fig. 1a has a diameter ranging from 1.5 to 2.5 times the wire diameter.
general guidelines application note an1002 www.cosemi.com in ball bonding, only gold au wire can be used while gold and aluminum al wires are used commonly in wedge bonding. this is because al wire will oxidize during the electronic flame off efo process to form the ball. for an au wire with a diameter less than 0.8bond mil

Environmental Protection and Health One
LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
To Improve the Purity Two
Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.
High Efficiency Three
LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
Low Cost Four
Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
