Coal Washery EPC Consultancy

Wrong Consultancy Advice Costs You Crores Every Year

Misaligned circuit design, equipment selection driven by vendor preference, and EPC oversight gaps leave recoverable coal on the reject pile and keep your plant below rated capacity for years.

John Finlay India’s coal washery EPC consultancy is backed by 130+ commissioned plants and 50 years of live operational data from CIL, SCCL, BCCL, and private mine-linked washeries across India, Australia, and China.

The Challenge & Our Answer

What Weak Coal Washery Consultancy Actually Costs You

Where Poor Consultancy Fails Your Plant

The Problem

Yield losses of 8–15% from undersized separation circuits and equipment selection mismatched to your ROM coal characteristics

EPC cost blowouts from consultants without live commissioning experience on-paper designs that fail at startup

DGMS statutory violations from plant designs that don't account for Indian regulatory requirements from day one

Magnetite losses 2–4× above design target from poorly specified dense media recovery circuits

Equipment vendor selection driven by commercial preference, not plant-specific process data and Tromp curve analysis

No provision for capacity expansion in original plant layout costly redesign within 5 years

Consultancy Grounded in 130+ Live Washeries

The JFI Solution

Data-driven circuit selection HMC, dense media bath, jigs, spirals, or flotation selected from your ROM coal float-sink analysis, not convention

Every JFI EPC engagement is led directly by engineers who have designed, built, and operated the plants they now consult on

Full DGMS CMR 2017 statutory compliance integrated from feasibility stage no surprises at inspection

Dense media circuit design targeting magnetite losses ≤0.5 kg/tonne from first commissioning shift

Vendor-neutral equipment selection tied to life-cycle cost and your coal's specific washability curve

Modular plant layouts pre-engineered for phased capacity expansion without full plant redesign

Core Service Scope

What John Finlay India Consultancy Delivers

The Consultant Behind the Results

John Finlay

With over 50 years in the coal industry, John Finlay is one of the most experienced coal washery EPC consultants in the world. His career spans greenfield plant design in Australia through to complex brownfield upgrades across India and China, with 130+ commissioned projects providing the operational data that informs every new engagement.

When an HMC cyclone underperforms, a JFI consultant doesn't just log the deviation. They trace it to the root cause, whether it is feed size distribution, SG creep, cyclone wear, or a blocked apex because they have the engineering background to distinguish between them. That is the difference.

50+ years of continuous coal industry experience across Australia, India, and China

Lead consultant on 130+ coal washery EPC projects thermal and coking coal configurations

Deep expertise in HMC, dense media bath, jigging, spirals, flotation, and dry beneficiation circuits

Patent-protected heavy media cyclone geometry optimised for Indian high-ash coal characteristics

Active projects with CIL, SCCL, BCCL, and private mine-linked washeries across India

Coal Washery Equipment Consultancy

John Finlay India's unique position as both a coal washery EPC consultant and a patent-protected equipment manufacturer means our equipment consultancy is backed by live production data, not vendor catalogs.

Dense Media Cyclone Selection

Patent-protected HMC geometry optimized for Indian high-ash coal. 25 mm–1000 mm diameter range. We manufacture these, our consultancy is built on real yield data.

Vibrating Screen Specification

Banana screen, D&R screen, linear and circular motion correctly specified for feed rate, top size, and dewatering duty. Undersized screens are the most common avoidable design error.

Magnetic Separator & Magnetite Recovery

99.5%+ magnetite recovery rate targets. Correct specification prevents magnetite losses running 2–4× above design, one of the highest silent costs in poorly consulted washeries.

Flotation Machine Circuit Design

Froth flotation for ultra-fine coal recovery and beneficiation. Cell sizing, reagent selection, and circuit configuration for site-specific ROM coal characteristics.

Centrifuge Selection for Coal Fines

Basket and scroll centrifuge selection for coal fines dewatering correctly matched to fines size distribution and target moisture specification for downstream handling.

Filter Press & Spiral Concentrator

Tailings dewatering and water recovery for washery circuits. Spiral concentrators for fine coal gravity separation. Site-specific selection based on slurry characteristics and discharge specification.
