1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are you managing gold recovery operations where declining ore grades and rising operational costs are squeezing your margins? Key challenges in material concentration and final recovery often include:

Inefficient Fine Gold Loss: Lên đến 1530% of micronsized gold particles can be lost in traditional sluices or jigs, representing a direct revenue drain with every ton processed.
Tiêu thụ nước cao: In arid regions or sites with strict environmental permits, conventional concentration methods can require over 200 gallons per ton, creating significant sourcing and tailings management costs.
Sự phụ thuộc của toán tử & Sự không nhất quán: Manual tuning and operation of concentration equipment lead to variable recovery rates, making grade control and production forecasting difficult.
Downtime for Concentrate CleanUp: Frequent shutdowns to manually clean up concentrates from tables or spirals halt your primary processing circuit, reducing overall plant availability.

How do you capture the maximum value from every ounce without exponentially increasing your water, năng lượng, và chi phí lao động? The solution lies in selecting the right primary concentration technology.

2. TỔNG QUAN SẢN PHẨM: Knelson Concentrators for Primary Gold Recovery

A Knelson Concentrator is a batchtype, centrifugal gravity concentration device designed for the recovery of free gold and other heavy minerals from grinding circuit slurries. Its core function is to achieve high mass rejection while retaining over 95% of free gold particles, producing a highgrade concentrate for further treatment.

Quy trình hoạt động:
1. Giới thiệu nguồn cấp dữ liệu: Slurry from the grinding mill cyclone underflow is introduced under pressure into the rotating cone.
2. Nồng độ ly tâm: As the cone spins at high speed (lên đến 200 lực lượng), centrifugal force pins heavy gold particles against the riffled lining.
3. Fluidized Bed Action: Continuous injection of fluidization water through the riffles creates a teetering bed, allowing dense gold to be trapped while lighter gangue material is flushed upward and out.
4. Giữ tập trung: Gold accumulates in the riffles throughout the batch cycle (tiêu biểu 30120 phút).
5. Xả tự động: At cycle end, rotation stops and the concentrated heavy fraction is automatically flushed to a secure collection point.

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Ideal for recovering free (giải phóng) vàng >30 microns in size from grinding circuits. Highly effective as a primary concentrator in both hard rock and alluvial operations.
Hạn chế: Less effective on flat or flaky gold particles. Hiệu suất giảm dần trên siêu mịn (<20 micron) gold without specific modifications. Requires a consistent feed density and pressure for optimal operation.
