NORDTECH runs your ore through bench tests, 1–5 t/h pilot lines and full-scale thickeners, separators and roasting systems — the same engineering team from first test to final plant. Our lab and pilot fleet has operated for leading international laboratories, a national key laboratory in China, and mine sites in Zambia. Every quotation is backed by test data, not catalogue curves.

Send a representative sample to our accredited partner lab in Shenyang. A standardized 8-step workflow takes it from receipt to a formal report — including the sedimentation test that sizes your thickener correctly. Preliminary assessment and sizing are free; physical test programs are quoted per sample, with the testing fee credited against your first order.
A lean engineering company built for small and mid-scale projects: fast decisions, direct access to the engineers who design your circuit, honest pricing.
Lab testing, process design, procurement and delivery supervision under one roof. One contract, one accountable partner — no finger-pointing between vendors.
Thickeners and magnetic separators are Nordtech's own designs, fabricated at long-term partner workshops to Nordtech drawings, with Nordtech inspection before shipment and brand-name key components throughout.
Modular manufacturing shortens on-site construction time and reduces installation risk in remote locations.
Overseas delivery experience across Africa, Central Asia and South America, with spare-part inventory and remote O&M support.
Send tank and process data for a free retrofit assessment, or a representative ore sample for an accredited lab test program (quoted per project). We return sizing, flow sheet and quotation with real test data behind it.
Yes — that is exactly how most clients start. Single lab machines (magnetic separators, samplers, thickeners, HPGR) ship in weeks, with rental available for selected dry separators and demagnetizers. Modular pilot lines of 1–5 t/h are quoted per flowsheet. The same fleet has operated for leading international mineral laboratories, a national deep-mining key laboratory in China, and mine sites in Zambia.
1–5 t/h depending on ore and flowsheet: a dry magnetic pilot line at 1 t/h, HPGR air-separation dry lines, tailings dry-stack and backfill lines, an integrated rotary kiln line at 1–2 t/h, and a 120 t/h steel slag line. All are skid-mounted on modular steel platforms, disassembled into containers, and reassembled on site in days.
Typical NORDTECH retrofits raise throughput and settling speed substantially, cut energy and flocculant consumption, and extend equipment life by years — without replacing the existing tank. The actual result depends on your current feedwell, rake and drive condition, which the on-site diagnosis measures first.
Paste thickeners discharge at 60–75% w/w underflow for paste-style high-density tailings, with diameters from 0.8 to 45 m, wall heights above 8 m, floor slopes of 30–45° and drive torque up to 9,600,000 Nm. Applications include tailings surface stacking, CCD washing circuits and mine backfill.
Through the sedimentation and flocculation test — step 7 of our standardized 8-step lab workflow. You send a representative slurry or ore sample; we measure settling behavior and flocculant response, then size the thickener from your own data and return the report with the quotation. Sizing from your existing plant data is free; a full physical test program is quoted per sample, and the testing fee is credited against your first equipment order.
Yes. Our full-particle-size dry magnetic separator range covers 20–350 mm lump waste rejection (NDT pulley, 3,500–8,000 Gauss), high-speed pre-separation at 400 t/h (NDGS), high-intensity cleaning at 7,000–11,000 Gauss (NDQG), fine-particle cleaning at −1.5 mm (NDCG) and super-fine separation at P80 = 0.025 mm (NDF) — all with zero water consumption and dry tailings discharge.
