The Operational Challenge

Why standard off-the-shelf solutions fail in mining.

Improper agitator selection, poor interstage screen maintenance, and carbon attrition from violent shear cause severe gold loss into tailings and excessive activated carbon consumption.

The Green Ngoria Engineering GuaranteeEvery flowsheet, tank geometry, and equipment configuration is validated through real laboratory testwork and mass-balanced for your specific ore lithology.

Systematic Execution

Our Engineering & Delivery Approach

We combine analytical process modeling with hands-on site metallurgy to achieve verified operational results.

01

Design tailored cascade leach and adsorption tank configurations with 24 to 36 hours of total residence time.

02

Deploy low-shear, high-efficiency dual axial hydrofoil agitators preserving 6x12 coconut shell carbon integrity.

03

Install high-capacity 316L wedge-wire interstage cylindrical screens and automated carbon transfer air-lift systems.

04

Coordinate complete loaded carbon acid washing, high-temperature Zadra elution, and electrowinning circuits.
