New multi-million dollar processing plant
that uses worlds best practice to produce concrete sand.
Plans began in 2015 to build a new processing plant.
From 2013 to 2022, approximately 240,000 tonnes of fine to medium sand/annum from Glen Forbes (along with 160,000 tonnes/annum of coarse sand from Grantville) were transported to the processing plant at The Gurdies site to be blended to achieve the ideal grading, then processed to produce concrete sand.
In 2015 plans began to build a new processing plant at Glen Forbes where our fine deposit is located. This resulted in a new multi million dollar processing plant opening in December 2022 at Glen Forbes. This new plant has a maximum washed sand output capacity of 300 tonnes/hour increasing our capacity by over 250%.
Today, approximately 360,000 tonnes of fine to medium sand is quarried at the site using a hydraulic excavator. Articulated dump trucks transport the raw sand to the processing plant at the site for blending to achieve the required grading, then washed and processed in the new processing plant that uses worlds best practice to produce concrete sand.
The new plant has improved efficiencies, including water recycling.
Our water recycling.
The plant uses efficient washing systems that are low in energy and water consumption.
The water used in processing operations is treated to remove sediment and recycled in a “closed loop water circuit” using a water clarifier/thickener.
The sediment is filtered and reduced to a “cake” in a continuous filtration process using belt filter presses. The filter cake recovered by filtration is mixed with oversize material and is transported by conveyor to quarry voids and is immediately used for backfilling as the first stage of rehabilitation.
Water soluble flocculants and coagulants are used to assist the water treatment and filtration processes. The flocculants and coagulants are identical to those used in the primary treatment of municipal water and are non-toxic and 100% biodegradable leaving no residue in backfill material.
Water recovered from stockpile drainage is all recycled for reuse in the processing plant.
