Graphite Plant Commissioning Series — Part 3: Cleaner 1 Flotation Cell Analysis

Following our previous updates on the successful commissioning of the 1,000 TPD graphite processing plant, today we take a closer look at the Cleaner 1 flotation cell in operation.

What you are seeing in this video is graphite's natural hydrophobicity at work. The froth is dense, dark, and heavily loaded — a direct result of graphite's strong affinity for air bubbles. The mechanical scraper is working to push this thick concentrate over the lip and into the launder.

Key observations:
→ High-grade concentrate indicated by uniform dark colouration and metallic sheen
→ Minimal visible gangue entrainment at the froth surface
→ Hyper-stable froth requiring mechanical removal — characteristic of graphite systems
→ Optimisation opportunities identified for reagent regime, feed density, and wash water implementation

This is what commissioning looks like in practice. The circuit is performing. The design is validated. Now begins the systematic optimisation phase — fine-tuning reagent dosages, adjusting operating parameters, and implementing wash water systems to push grade and recovery toward their theoretical maximums.

Process design is not just about getting the plant running. It is about building in the flexibility to optimise. That is what separates a good circuit from a great one.

Following the incredible response to our recent 1,000 TPD graphite plant commissioning update, we wanted to take you deeper into the technical core of what makes these projects successful: Process Flow Design.

In mineral processing, especially with graphite, the margin between success and failure lies in the flowsheet. Graphite is unique — the commercial value is heavily dependent on preserving flake size while achieving high purity. You cannot simply crush and grind it like a base metal ore without destroying its value.

At Nesch Mintech Global, our approach to process flow design is built on rigorous metallurgical testing and precise engineering. As you can see in this commissioning footage, every stage — from the primary grinding circuit (carefully calibrated to liberate flakes without over-grinding) to the material handling and flotation stages — must work in perfect harmony.

Our technical capabilities in process flow design ensure:
🔹 Optimised Comminution — selecting the right mill type and operating parameters to maximise flake preservation.
🔹 Efficient Material Handling — designing conveyor and feed systems that maintain steady-state operations under load.
🔹 Scalable Flotation Circuits — engineering separation stages that deliver the required purity grades consistently.
🔹 Seamless Commissioning — translating bench-scale metallurgical data into robust, operational plant reality.

A well-designed flowsheet doesn't just process ore; it protects your project's economics. We take pride in delivering complete solutions from bench scale to full production.

Are you developing a graphite project or looking to optimise an existing circuit? Let's discuss how our process design and metallurgical testing capabilities can de-risk your operation.

Bankable Feasibility Study! 🤑 🫢

In the past few weeks, I’ve received several questions from investors and licence holders about Bankable Feasibility Studies (BFS)—what they cost, how much land is needed, who buys the project afterwards, and whether it’s worth doing one for gold. These are important questions for anyone serious about developing a mining asset.

What does a Bankable Feasibility Study cost?
A BFS is the highest level of technical and financial confidence in mining. Depending on the scale and complexity, costs typically range from USD 1.5M to 15M+. It includes mine design, metallurgy, geotechnical work, environmental studies, tailings design, and full financial modelling.

How big should the land be?
There is no fixed requirement. The land must simply cover the orebody and all mine infrastructure—processing plant, tailings facility, waste dumps, water dams, workshops, and buffer zones.
Small underground mines may need 5–20 ha
Medium open pits may require 200–500 ha

Who buys a project after a positive BFS?
A BFS transforms a licence into a financeable asset, attracting:
Mid‑tier and major mining companies
Private equity mining funds
Royalty and streaming companies
Strategic investors and regional operators

How are fees charged when a buyer is found?
Industry‑standard models include:
A success fee (1–5% of transaction value)
A finder’s fee for introductions
A technical advisory fee for data room preparation and due diligence support
Transparent structures protect both sides and maintain professional integrity.

Is it worth doing a feasibility study for gold?
Yes—when the project has real geological potential. A BFS is not a gamble; it is a value‑creation tool. If the resource is too small or poorly defined, it’s better to invest in drilling and resource definition first. When the geology is strong, a BFS can significantly increase project value and attract serious capital.

Mining decisions must be both technical and strategic. A well‑executed feasibility study often determines whether a licence becomes a long‑term asset or remains just a piece of paper.

If you’re serious about moving your mining project forward, understanding these fundamentals isn’t optional—it’s critical. A BFS is your ticket from exploration to enterprise. Got questions? Let’s talk about where your project stands and what’s next.
