We buy zinc concentrate
G-MTW buys zinc concentrate at source for mining holdings and smelters. Zinc is the galvanising metal, and its demand tracks infrastructure — considerably steadier consumption than other metals.
What we buy
- Material: zinc concentrate
- Grade: 50-55% Zn
- Minimum volume: from 100 MT
- Tell us your monthly capacity as well — we handle both one-off lots and recurring supply
Mandatory specification
The maximums our buyers accept, common to every mineral:
| Element | Maximum accepted |
|---|---|
| Arsenic (As) | < 0.5% |
| Mercury (Hg) | < 0.005% |
| Cadmium (Cd) | < 0.005% |
| Sulphur (S) | < 9% |
| Fluorine (F) | < 0.10% |
| Moisture | < 5% |
| Particle size | 20-40 mm |
Dry basis, backed by laboratory analysis. In zinc, pay particular attention to cadmium: it occurs naturally alongside the mineralisation and it is one of the tightest limits on the list. Full detail on our specification page.
