Copper Rougher Flotation | Improving Recovery and Concentrate Grade

When processing low-grade copper ore, selecting the right collector can make a significant difference in both metal recovery and concentrate quality.

At Y&X, we go beyond supplying conventional flotation reagents. Through continuous product development, customized reagent formulations, and technical evaluation, we help mining operations identify more effective flotation solutions for their specific ores.

A recent customer evaluation in Peru provides a promising example.

Seven Y&X collector formulations were evaluated on copper ore with a head grade of just 0.56% Cu, benchmarked against the customer's existing reagent under rougher flotation conditions.

Three Y&X collectors demonstrated particularly strong performance:
• YX09510C: 80.4% Cu recovery at 8.3% Cu grade — the highest copper recovery in the test series.
• YX-C: 80.0% Cu recovery at 8.9% Cu grade — the highest copper concentrate grade.
• TS-C1: 79.4% Cu recovery at 8.4% Cu grade — a promising balance of recovery and grade.

By comparison, the customer's reference collector achieved 76.7–77.8% Cu recovery and 7.9–8.0% Cu grade across two tests.

Notably, YX09510C achieved 2.6 percentage points higher copper recovery than the stronger reference result, while YX-C delivered improvements in both recovery and concentrate grade.

What makes the difference?

Different ores require different reagent strategies. Rather than relying on a single collector formulation, Y&X develops and evaluates a range of flotation chemistries to address different mineral characteristics and processing objectives.

Our technical approach focuses on recovery, selectivity, flotation kinetics, and reagent performance — helping customers identify suitable candidates for further testing and optimization.

These initial results demonstrate the potential of our collector portfolio. Further testing and economic evaluation will help determine the most suitable solution for practical application.

Iron Ore Reverse Flotation | On-Site Flotation Circuit Monitoring

Our technical team recently visited a customer's iron ore processing plant to provide on-site technical support for its reverse flotation circuit. During the on-site trials of our reverse flotation collector, our technical team monitored froth behavior across the rougher and cleaner stages to evaluate the circuit's response to the reagent and identify opportunities for further optimization.

In reverse flotation, the collector plays a critical role in selectively floating silica-bearing gangue minerals while keeping valuable iron minerals in the non-floated product.

At Y&X, we offer specialized reverse flotation collectors for iron ore processing, helping operators optimize silica removal, reagent consumption, and overall separation performance.

Customer testing at a Russian mine provided encouraging results for Y&X's Q30B frother:

▪ Average recovery of 90.3% at a concentrate mass yield of 20.55%
▪ Optimal dosage identified at 70 g/t
▪ Further increases in dosage offered no additional benefit under the tested conditions

The report concluded that Q30B met the flotation requirements and could be considered a potential alternative to MIBC.

Finding the right frother—and the right dosage—starts with testing your ore.

The next recovery opportunity may already be in your tailings.

Tailings re-flotation aims to recover valuable minerals remaining after the original processing stage. This infographic illustrates a simplified circuit, the equipment involved, and the separation mechanism inside a flotation cell.

Each stage has a specific role:
• Conditioning — adjust pulp conditions and allow flotation reagents to interact with mineral surfaces.
• Roughing — recover valuable minerals into a rougher concentrate.
• Cleaning — upgrade the concentrate by rejecting unwanted material.
• Scavenging — recover additional valuable minerals from the rougher tailings.

In this example, cleaner tailings and scavenger concentrate return to the rougher feed for further treatment.

Inside the flotation cell, separation depends on particle–bubble attachment. Hydrophobic mineral particles attach to air bubbles, rise into the froth layer, and are collected as concentrate.

Reagents help control this process: collectors enhance the hydrophobicity of target mineral surfaces, frothers regulate bubbles and froth stability, and modifiers adjust conditions such as pH and flotation selectivity.

Regrinding is an option when further mineral liberation is needed. Its suitability, together with the flowsheet and reagent scheme, should be evaluated through testwork.

At Y&X, we support flotation reagent selection, laboratory testing, and technical troubleshooting for mineral recovery projects. Working on tailings reprocessing? Let's discuss your feed characteristics and testing objectives.

Las Bambas Mine, Peru – Technical Case Study II: Analysis
Molybdenum recovery rose from 56.5% to 61.5% in a copper–molybdenum ore test. The key difference? Clay depressant selection.
A laboratory rougher flotation study using ore from the Las Bambas mine in Peru compared three Y&X clay depressants: D486, D417 and D417S.
Alongside copper performance, the study tracked how much associated molybdenum reported to the rougher concentrate—and how quickly it was recovered.
The feed contained 104.90 ppm Mo. Each depressant was tested at 100 g/t, with pH 8.8 and a grind size of P80 = 230 μm.
The molybdenum results:
• Benchmark: 56.5% recovery
• D486: 53.7% recovery
• D417: 59.1% and 61.5% recovery in two tests
• D417S: 54.4% recovery
D417 delivered a recovery increase of 2.6–5.0 percentage points over the benchmark, with stronger early-stage molybdenum recovery shown in the flotation curves.
Mo grades in the two D417 rougher concentrates were 1,139.4 and 1,183.4 ppm, compared with 1,194.6 ppm for the benchmark.
An important finding for reagent selection: D417S achieved the highest copper recovery, while D417 achieved the highest molybdenum recovery. Evaluating both metals gave a more complete picture of reagent performance.
Does your reagent screening give by-product recovery the same attention as the primary metal?

Las Bambas Mine, Peru – Technical Case Study I: Analysis

Copper recovery increased from 77.5% to 78.5%. What changed—and what happened to concentrate grade?

In a laboratory study using ore from the Las Bambas mine in Peru, three Y&X clay depressants—D486, D417 and D417S—were evaluated against a benchmark in rougher flotation. The aim was to understand how depressant selection affected recovery, concentrate grade and flotation kinetics under conditions based on the mining operation.

The ore contained 0.56% Cu. Tests were conducted at pH 8.8, with a grind size of P80 = 230 μm and a dosage of 100 g/t for each evaluated depressant.

The copper results:
• Benchmark: 77.5% recovery | 8.6% Cu grade
• D486: 77.7% recovery | 8.2% Cu grade
• D417: 78.1–78.3% recovery | 7.8–7.9% Cu grade across two tests
• D417S: 78.5% recovery | 8.1% Cu grade

D417S achieved the highest final copper recovery, gaining 1.0 percentage point over the benchmark. Mass pull increased from 5.0% to 5.5%, while concentrate grade decreased.

The practical lesson: recovery, grade and mass pull need to be assessed together. These laboratory results support further testing to confirm repeatability and understand the implications for downstream cleaning. When screening reagents for your copper circuit, which is the greater priority: additional recovery or higher concentrate grade?
