Minera Centinela is owned by Antofagasta PLC and processes ore from four open pit deposits: Esperanza, Central Treasury, Northeast Treasury and Mirador, from which it produces copper in cathodes and concentrates, in addition to gold as the main by-product. In 2019 it produced 276,000 tonnes of copper and 222,600 oz of gold from the treatment of approximately 30,000,000 tonnes of ore
The optimal condition for the allocation of flotation classification sand is to ensure the mode of sand unloading from the bed (solid mass fraction 55–60%), formed at the flotation classifier bottom. This paper also presents the examples of full-scale testing of these classifiers on the copper-zinc concentrating plants. The use of flotation classification in closed ore grinding circuit

grinding circuit sabc. Several large tonnage copper porphyry plants in Chile use an opencircuit SAG configuration where the pebble crusher product is directed to the ball mills SABCB circuit The original grinding circuit at Los Bronces is an example the pebbles generated in the two SAG mills are crushed in a satellite pebble crushing plant and then are conveyed to the three ball mills Mogla
Hence, rougher circuit operating without or small amount of lime, and depression of pyrite in cleaning stages at low pH, are the key factors for the Cu-Mo-Fe flotation technology in seawater. This scheme is completely different from the traditional one in fresh water, which applies in the rougher circuit a pH

Flotation Circuit Esperanza. 2892010 new hsc chemistry software from outotec incorporates a new simulation module that can assist with flotation circuit performance optimisation in flotation plantsptimising flotation circuit performance is difficult without addressing factors such as flotation plant operation, throughput, recovery.
Rather than design the SAG circuit with an arbitrary fraction of total circuit power, it is more useful to base the required SAG mill size on the product of the unit power requirement for the ore and the desired throughput. Subsequently, the size of the secondary milling circuit is then sized based on the amount of finish grinding for the SAG circuit product that is required. Restated, the
Good Quality Fine Gold Ore Flotation Cells. 2019-10-24chemical composition of gold particles and associations with other minerals affect gold recovery by flotationn general, gold-pyrite or gold-copper minerals associations have no problems and gold can be recovered without major problemhe lack of good liberation is a problem and the comminution circuit is the key element.
The Esperanza South underground mine lies to the south-west of the existing Mammoth workings and comprises an independent decline and supporting mine infrastructure. The current processing unit comprises a conventional copper sulphide flotation concentrator. The existing equipment is refurbished and a regrind mill has been added to allow the plant to process up to 1.7Mtpa of ore from multiple
