The milled product cyclone overflow is treated in a flotation circuit that produces a copper-gold concentrate for export. Treatment of the concentrate includes regrinding to a P 80 of 25 microns and 3 stages of cleaning to achieve an acceptable grade. The final concentrate is thickened and filtered, then trucked to a port located in Bunbury ...

The Gerber format is an open 2D binary vector image file format. It is the standard format used by the printed circuit board PCB industry software to describe the printed circuit board images copper layers, solder mask, legend, etc. All PCB orders require a set of Gerber files.
Milling. Another way to make a circuit board is to use a mill. A mill is a drill that moves in many directions. The drill removes a small amount of copper each time it moves. The mill removes the copper around the wires on the board. This leaves extra copper on the board. Other methods do not leave the extra copper on the board.
Note The Gerber file must be related to the mirrored printed circuit board in the same way that the copper side usually defined as Bottom Copper remains face-up, necessary condition for a correct milling. From the File menu, select Open gerber and open the files relating to the tracks e.g. Bottom Copper

To control my CNC Mill I use Mach 3, but any other software can be used such as LinuxCNC and EMC2. But for me I think the 175 for a Mach 3 License is well spend since its a great peace of software. I also got an license for CopperCAM for 80 which is good given out and dont have to mangle with a lot of conversation programs and scripts.
This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. JKSimMet simulations were used to test various operating and design conditions to improve the comminution process.

files describe various board images, such as copper layers, solder mask, silkscreen, and paste mask. This data includes traces, vias, pads, component footprints, and planes, as well as drilling and milling data. RS-274X is the middle child of the three Gerber file formats. The oldest format for Gerber files is RS-274D, or

Copper is a relatively soft and malleable metal with excel-lent formability, making it ideal for architectural applica-tions such as roofs, wall cladding, gutters and downspouts. Additions of other elements to copper strengthen it and form copper alloys, including brasses, phosphor bronzes and copper nickels. Copper alloys possess tensile ...

The metallic copper may have a coating that is interfering with the collector. This might be removed by attrition. Depending on the amount and size of this native copper it could be building a circulating load in the milling circuit. This could be recovered by gravity methods from a bleed stream of the cyclone underflow.
