mining australian sapphires
Australian sapphire mining on the Central Highlands Gemfields in Queensland is a small‑scale, low‑impact process that begins 15-40 feet underground, where sapphire‑bearing wash is carefully hand‑dug on mining claims strictly governed by the Queensland Government to ensure safe, tidy and responsible practices.
Using only an electric jackhammer, picks, shovels, a wheelbarrow and a generator‑powered setup. The dirt is brought to the surface via an electric Up & Over bucket before being processed through an electric trommel that washes and separates sand and larger rocks. The remaining screened wash then moves through a pulsator - a six‑tray jigging system where the natural weight of sapphires allows them to sink while lighter material flows away.
Leaving behind the heavy concentrate of sapphires and ironstone. Throughout the entire process, water is continuously recycled through a de‑waterer and settling tanks, requiring only occasional top‑ups and keeping the operation clean and efficient. This careful, hands‑on method results in minimal ground disturbance, strong environmental stewardship, and fully traceable Australian sapphires from mine to market.
