Lower-pH Copper Flotation Reagent System

2020-12-18 · Home » Lower-pH Copper Flotation Reagent System In the mining industry, flotation is a process that concentrates minerals from their ores prior to metal recovery. Current practice uses slurry pHs in excess of 10, achieved by adding burnt lime (CaO).

Recovery Copper from a Low Grade and Ultra-Fine

The present study aims to characterize the copper ore from east area of Yunnan province. The results indicate that the ores is a representative low grade and and ultra-fine-grained ore. As a result, a suitable flotation flow i.e. “ultrafine grinding- sulphidizing and dispersing bulk flotation with low dosage collector” was presented for processing of eligible copper concentrate with high

Separation efficiency improvement of a low grade copper

2017-12-21 · The recovery of gold-containing pyrite to the copper concentrate is encouraged to achieve a higher total gold recovery provided that a saleable copper concentrate grade is still produced. Mineralogical diagnosis of feed and product streams from the copper flotation circuit have shown that the copper bearing minerals are well liberated

Copper Recovery from Silicate-Containing Low-Grade

Copper Recovery from Silicate-Containing Low-Grade Copper Ore Using Flotation Followed by High-Pressure Oxidative Leaching Vol. 64, No. 1 (21) 5 acid (H 2 SO 4) were used in this study. The silicate- containing low-grade copper ore samples were first introduced into the flotation cell with 500 mL water under constant stripping (1000 rpm) to pre-

Flotation Circuit: Concentrate Grade and Recovery

The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.

A New Collector for Effectively Increasing Recovery in

A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and microscopic imagery as well as economic feasibility analysis.

Ultrasound treatment on tailings to enhance copper

a b s t r a c t As ore grades fall, the amount of tailings production for the same copper production is expected to rise. Flotation recovery of copper sulfide from the El Teniente plant has deteriorated in recent years, in this regard ultrasound treatment of tailings for enhanced copper recovery was evaluated in laboratory experiments.
