Namibia's gold mining sector is undergoing a massive transformation, driven by rising global demand, infrastructure investments, and a geological landscape rich in both primary shear-hosted and alluvial deposits. The country is home to key gold-bearing structures, notably within the Damara Orogenic Belt, featuring prominent deposits like the Navachab mine near Karibib and B2Gold's Otjikoto mine in the Otjozondjupa region.
The primary gold deposits in Namibia typically consist of low-grade, high-tonnage sheeted quartz-vein systems and auriferous skarns. Mineralization is often characterized by very fine-grained gold encapsulated within quartz veins, sulfides (pyrite, arsenopyrite), and occasionally bismuth and tellurium alloys. This mineralization profile dictates the necessity for efficient, fine-grinding systems like high-capacity ball mills and wet pan mills, combined with centrifugal gravity concentrators capable of catching ultra-fine particles (under 74 microns) prior to downstream leaching or flotation.
Building a processing plant for Namibian conditions requires a precise balance of mechanical efficiency, wear-resistance (due to highly abrasive quartzitic ores), and environmental compliance. Our engineered solutions are divided into modular stages to maximize recovery and limit site footprint.
| Processing Stage | Equipment Employed | Target Output Size | Primary Benefit |
|---|---|---|---|
| Primary Crushing | Diesel Engine Jaw Crusher / Spring Cone Crusher | 0 - 25 mm | Reduces run-of-mine ore; diesel-driven options ideal for remote Namibian sites. |
| Secondary Fine Grinding | Ball Mill / Wet Pan Mill | 200 Mesh (74μm) up to 85% passing | Liberates gold flakes locked inside quartz veins or sulfide complexes. |
| Gravity Concentration | Knelson Centrifugal Concentrator / Kacha Concentrator | Heavy mineral concentrate | Recovers up to 90% of free gold instantly without chemical usage. |
| Sieve & Classification | Spiral Classifier / Trommel Screen | Sized feed stream | Prevents over-grinding, returning oversize particles to the mill circuit. |
With environmental permits under Namibia's Environmental Management Act of 2007 becoming increasingly rigorous, gravity separation has gained immense traction. Centrifugal concentrators exert artificial G-forces (often up to 60G-120G) to separate high-density gold from lighter silicate host rock. This physical method completely circumvents the use of toxic mercury, making it the preferred technical route for artisanal and mid-scale operators seeking rapid permitting approvals from the Ministry of Environment, Forestry and Tourism.
We supply modular, scalable gold processing systems built to thrive in harsh environments. By combining crushing, milling, and gravity recovery circuits into a unified footprint, we enable mines to begin operations rapidly. Our designs focus on water conservation, with integrated water recycling units to ensure operations in the arid Erongo and Kunene regions remain highly sustainable.

Learn More About UsThe foremost challenge in Namibia is severe water scarcity, followed by the highly abrasive, quartz-heavy nature of the ore. Our processing plants address this by incorporating low-water centrifugal gravity concentrators (such as Knelson and Kacha concentrators) and dynamic wastewater recovery thickeners. For quartz hardness, we utilize specialized high-manganese cast alloys in our jaw and cone crushers to maximize service life and reduce downtime.
Yes. In line with the Minamata Convention on Mercury and Namibia's strict environmental regulations, our plants focus on gravity beneficiation. By utilizing centrifugal concentrators, sluice boxes, and shaking tables, we achieve up to 90% primary gold recovery physically, without using mercury or cyanide.
We routinely manage complete logistics from our factory in China to the Port of Walvis Bay. All machinery is treated with anti-rust coatings and securely packed in containers or heavy duty flat racks. We supply full documentation (Bill of Lading, Certificate of Origin, packing list) to ensure smooth customs clearance through local Namibian agencies.
Ascend provides complete engineering support, including layout drawing and foundation design. We can dispatch certified installation engineers to your mining site (in areas such as Erongo, Otjozondjupa, or Karibib) to oversee structural assembly, electrical wiring, wet tests, and local operator training.
