Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated

Mineral Processing an overview | ScienceDirect Topics
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods
Lime use and functionality in sulphide mineral flotation
Processing plants for porphyry copper ores are generally very large, processing up to 200,000 tpd of ore (JX Nippon, 2018)), and emphasis is put on throughput Ores with low pyrite content (<2%) are generally considered easier to process (and the reagents scheme only includes copper collectors, pH regulator, and frother)

COPPER Copper production TU Delft
Flotation of nonsulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated

Milling Process, Defects, Equipment
Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material The milling process requires a milling machine, workpiece, fixture, and cutter The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached
