Evidence status: Reference case prepared from user-supplied project notes. Keep noindex until quotation evidence, technical drawings and approval for public publication are confirmed.
Project positioning
This reference is useful for rock gold clients who already have some front-end crushing and want a gravity-focused fine-gold recovery route with water recycling and limited civil work.
The supplied notes describe a client who did not like using a ball mill. That constraint changes the process discussion: liberation and fine-gold recovery must be checked carefully before the route is treated as repeatable.
Known project facts
- Mineral: rock gold
- Location: Australia
- Nominal capacity: 30 TPH
- Feed condition: 400 mm rock had already been reduced to minus 80 mm by a mobile crushing station
- Target liberation / recovery size noted: 0-2 mm
- Client requirements: suitable for fine gold particles, tailings water circulation and lower civil construction cost
Process route
The route described in the supplied notes follows:
- Feeding and controlled crushing.
- Screening to control the gravity feed.
- Gravity beneficiation for the fine-gold fraction.
- Tailings dewatering and water return.
- Smelting support for final concentrate handling.
Equipment scope
The notes referenced a fine jaw crusher, high-pressure roller crusher, vibrating screen, mixing tank, slurry pump, centrifugal concentrator, shaking table, sluice, fine sand recovery machine and gold melting furnace.
Specific quotation examples included PEX250 x 1200 fine jaw crusher, 800 x 600 high-pressure roller crusher, 4/3 inch slurry pump, 4500 shaking table, 60 centrifugal concentrator and 35A melting furnace.
Quotation and design lessons
This type of project needs more confirmation than a simple equipment list:
- Whether steel structure is included
- Whether PLC control is required
- Tailings water circulation scope
- Guards, covers and site safety requirements
- Electrical cabinet standard
- Pump duty and slurry handling
- Installation spares and commissioning support
Publication status
This is not a published performance claim. It is a reference structure for discussing a similar fine-gold gravity route when the ore has already been partially crushed.
