Gold processing plants are never copy-paste designs. Every deposit writes its own rules – ore mineralogy, clay behaviour, gravity-recoverable gold, sulphide association, water quality, cyanide response, tailings characteristics, climate and logistics. What works cleanly at one site can quietly destroy recovery at the next.

This principle is being tested in full at one of our current projects: an 1000 TPD carbon-in-leach (CIL) gold plant under construction at altitude in Kyrgyzstan. Set against the Tien Shan mountains, the plant integrates gravity concentration, CIL and Merrill-Crowe circuits in one of the more demanding logistics and climate environments Tanka has worked in.

Building at altitude sharpens one discipline above all: designing for the ore and the conditions in front of you, not the plant that worked last time. Thin air, temperature extremes, extended supply lines and a short construction window each impose their own constraints on equipment selection, circuit design and execution sequencing – constraints that must be engineered for from the outset rather than corrected during commissioning.

Tanka’s role spans the full arc of delivery: testwork review and flowsheet development, gravity and CIL circuit design, detoxification, tailings, plant layout, procurement support and commissioning. Across each stage, the objective remains the same – making recovery, reliability and plant stability hold consistently at site, under real operating conditions.

Because successful gold processing is not only about designing a plant. It is about making it work.
