200TPH Placer Gold Mixed 20TPH Rock Gold Processing solutions

This is a full setup of a 200 TPH placer gold mixed with 20 TPH rock gold processing plant. According to the characteristics of mixed gold ore, an efficient washing + gravity separation combined process is adopted to ensure high gold recovery rate while reducing energy consumption and operating costs. The whole plant includes two parts: an alluvial gold processing solution and a rock gold processing solution. For alluvial gold plant, including washing, screening, and gravity separation systems. For rock gold lines, including crushing and gravity separation systems.

The raw material conditions are as below:

The raw materials are 0-70mm, have a lot of sticky clay, mixed soil and rock gold ore.
There are 90% alluvial gold ore and 10% rock gold ore in raw material.
The free gold particle size range in alluvial ore is 0-5mm.
The gold rock needs to be milled to 2mm to maximum liberate inside fine gold.
The processing capacity for an alluvial gold line is 200 tons per hour, and for the rock gold line is 20 tons per hour.

Placer Gold & Mixed Rock Gold Processing Flow

1. Alluvial Gold Processing Solution(200 TPH)

(1) Feed System:

Hopper + Vibrating Feeder – Receives 0-70mm raw material and ensures consistent feeding.
Belt Conveyor – Transports material to the trommel scrubber.

(2) Scrubbing & Screening

Trommel scrubber – Removes sticky clay and screens the material into:0-5mm gold-bearing fraction, 5-70mm sent to rock gold processing line.

(3) Gravity Concentration

Centrifugal concentrator (Falcon/Knelson) – Recovers >95% of free gold from the 0-5mm fraction.
Sluice Box – Captures remaining coarse gold from tailings.
Shaking tables – Further upgrades concentrate from the centrifuges and sluice.

(4) Tailings & Water Recycling

Spiral dewatering machine + vibrating dewatering screen – Ensures dry tailings and recycled process water.

(5) Gold Refining

Amalgamator + gold melting furnace – Produces high-purity gold bars (Au >99%).

2. Hard Rock Gold Processing Solution(20 TPH)

(1) Crushing System

Hammer Crusher – Reduces 5-70mm rock to 0-2mm slurry for efficient liberation.

(2) Concentration & Shared Equipment

Same Centrifugal Concentrator + Shaking Table System – Ensures cost-effective gold recovery.

Through the operation of this mixed placer & rock gold processing plant, the customer has achieved efficient gold ore processing. The recovery rate of placer gold is ≥96%, and the recovery rate of rock gold is ≥90%, both of which have reached the industry-leading level. At the same time, the water recycling system effectively reduces the consumption of water resources and reduces production costs. In addition, the entire gold plant has a high degree of automation and is easy to operate, which greatly improves production efficiency. JXSC can provide customized mineral processing solutions based on the raw material characteristics, production scale, and quality requirements of different customers. Whether it is a complex polymetallic ore or a single gold ore, contact us to design efficient, environmentally friendly, and economical gold processing solutions.
