Sulfide ore beneficiation is a major challenge for the mining industry. Recovery of valuable minerals such as copper, lead-zinc or nickel from sulfide-bearing ores requires complex and costly processes with a wide range of potential risks. These challenges can include the presence of harmful gases such as hydrogen sulfide and …
In recent years, developments in control strategy for banks of flotation cells have included process control based on mass pull. Mass pull, or the flowrate of solids reporting to the concentrate, is affected by changes in froth structure and stability which are in turn affected by changes in operating parameters such as air flowrate and froth depth. ...
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.

The design of the Phu Kham plant was a compromise between high copper recovery and the risk of meeting acceptable final concentrate grade. A high recovery bulk rougher flotation design concept was developed during the pre-feasibility study, but difficulty in achieving a 24% copper concentrate
Obtaining high recovery in copper flotation plants has been always under investigation in recent years. Misreported copper into tailing dramatically declines copper recovery. This study aims to ...
The Pineer froth flotation process enables sustainable and cost-effective copper/lead/zinc ore recovery. Comes from one supplier, responsible for the whole package. Provides mechanical and performance guarantees for the entire plant unit, …
Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...
A large porphyry copper flotation plant has been simulated using a flotation model developed from first principles using the hydrophobic force as a kinetic parameter (Huang et al., 2022, Gupta et al., 2022).The input to the simulation was the size-by-class liberation matrix (m ij) of a flotation feed, which was essential for predicting the …
Sedgman supported the recovery of a high-grade copper concentrate from oxide and sulphide mineralisation through a 1.0 Mt/a flotation plant in the Democratic Republic of Congo (DRC).
Copper and molybdenum recovery data for a one year period of a typical porphyry copper flotation plant are reported in Fig. 1, showing high variability of molybdenum recovery with time. Download: Download full-size image; Fig. 1. Historical recovery data for a typical porphyry copper plant. Bulk copper/molybdenum …
This project is a "Copper flotation" project with some Moly (<200ppm). The chosen scale-up was 2.5 while The Book calls for on copper 2.1X. Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.
The concentrate is later smelted to obtain copper and gold separately. Most copper flotation plants, however, are optimised for copper recovery in terms of collector selection for surface hydrophobisation, under the assumption that gold will behave in a similar manner (Bulatovic, 1997).
A flotation plant is being erected at the Falcon mine, Rhodesia, to treat ore containing gold and copper. With the exception of the Mt. Morgan, the Etheridge, ... containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried …
A maximum recovery of copper was 88,58% while the grade was 2,88 with 32,29 copper oxide on the total massive copper under the flotation conditions: 1,15 pulp density, 10 g/t dosage collector, 10 g/t dosage frother, and 50 g/t dosage dispersant and the maximum grade 12,24 while the recovery was 47,02% under the flotation conditions: …
To recover copper and molybdenum from their porphyry sulfide ores, several process flowsheets are applied, and two of them are shown in Fig. 1.[23, 24] As illustrated in Fig. 1 (a), [23, 25] the two-stage flotation flowsheet is the most widely adopted.In the first stage, copper and molybdenum sulfide concentrates are recovered together.
Obtaining high recovery in copper flotation plants has been always under investigation in recent years. Misreported copper into tailing dramatically declines …
In Madenköy Plant, flotation is applied as an enrichment method. After liberation of associated minerals, copper ores are floated by froth flotation. Then, the copper concentrate is obtained selectively. The flotation process has a typical flowsheet which include rougher flotation, rougher scavenger, middling, regrinding and 3 stage cleaner ...
Conventional flotation plant optimization procedures for copper and copper–gold ores have served the industry well over decades. But with the present trend in declining ore grades along with increase in metallurgical complexity, many flotation operations are experiencing significant challenges in sustaining design or operational …
The feed to a flotation plant assays 0.8% Cu. The concentrate produced assays 25% Cu, and the tailings 0.15% Cu. Calculate; i) The recovery of copper to the concentrate. ii) The ratio of copper concentrate. iii) The enrichment ratio

A sharp increase in copper recovery is observed at pH < 3. • The achieved copper recovery of 12% for 2 h with tap water, points to the possibility of natural dissolution of copper from the tailings due to the presence of copper oxides or copper sulphate in it. • Iron dissolution was observed only at pH values lower than 1.5 and can …
At present, in Huili dressing plant, the raw sample has been treated by the different flotation of lead-zinc sulfide flotation under high-alkaline pH conditions (pH = 12±), then the zinc oxide minerals recovered from Pb Zn flotation tailings is firstly pretreated by de-sulfurization flotation, physical de-sliming process, following the ...
