Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.
Mills usually have motors in the following range: SAG mill motor: 7,435 kW or an HPGR circuit with motors: Ball mill 1 (4,015 kW) and Ball mill 2 (4,152 kW) for a porphyry copper molybdenum mine. Comparing mill operations for both open pit mining to underground mining, where the metal is separated from rock ore containing the metal mined, both ...

SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42'' () in diameter, powered by a 28 MW (38,000 HP) motor.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
the correct power required to grind ore in a SAG mill, by developing ore hardness variability functions for the ore body to be mined. This paper describes the next step in the SAG design process, which is choosing a SAG mill to accomplish the required specified design performance.

1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
trommel screen will be conveyed to the SAG mill grinding circuit. Oversize will be sent to the pebble crusher for further processing and then returned to the SAG mill. Material from the SAG mill undergoes a floatation process to produce copper and molybdenum mineral concentrate slurries which will then be transported to the dewatering circuits.

After mining, Copper Oxide ore delivered to the ROM stockpiles is fed into the processing plant through a mineral sizer followed by a semiautogenous grinding mill (SAG mill). Copper is produced primarily by an agitated leach, counter current decantation and solvent extraction and electrowinning (SXEX) process.
