The United Nations has reported that along with sand, crushed rock and gravel collectively account for the largest volume of solid material resources extracted with between 40bn and 50bn tonnes extracted each year. “They can get it down to a thickness of 3mm, which will make electric cars lighter.” “They are developing Gorilla Glass that can be moulded and curved to replace windscreens, particularly for electric vehicles. He highlighted Corning’s Gorilla Glass, which is typically used for smartphone screens, as an example. Maluish added that glass manufacturers such as Corning and China Southern Glass, invest in a lot of research and development into new glass products. They require a high-quality glass, which needs high-quality sand,” he noted, adding that people are surrounded by silica sand products without even realising it. “There’s a current shortage of vials for vaccines. Speaking to Stockhead, VRX Silica (ASX:VRX)managing director Bruce Maluish highlighted some of these specialised uses, one of which is especially relevant as the world continues to grapple with the COVID-19 pandemic. Higher purity sands are also used for a wide range of applications in the foundry and glass industries. Silica sand is one of the most mined commodities in the world thanks to its angular particles that are capable of interlocking and providing greater load bearing capacity, which makes it valuable for land reclamation and the manufacture of concrete. Renowned investor Tolga Kumova has also twigged on to its potential, noting that the sector is starting to emerge in Western Australia and that it would grow much larger over the next couple of years. Dried materials are stored in storage tanks or transport packaging.Silica sand is a bulk commodity that has only recently starting breaking into the collective consciousness of Australian investors as awareness grows about strong Asian demand and dwindling supplies.
Moist sands are dried in modern sand dryers, and subsequently cooled down in a cooling pocess. Following the classification, sands and gravels are transported to process boxes and after dehydration, they leave for dispatch boxes.Īfter separation of sand fractions and sedimentation without adding chemicals, Kaolin is formed and subsequently pressed in chamber presses. Compressed kaolin is stored in a dry environment to prevent it from regaining moisture again. The raw material is processed using a hydraulic classification method. This is why the company consists of two separate production complexes today:īoth deposits provide slightly weathered sandstone dating to the Cretaceous period. This exclusively Polish capital accelerated the pace of the sand plant´s development, which today includes two production complexes in Grudzeń Las and Syski.īased on our Polish and internatioanal customers' high demands on silica moulding sand, glass sand and filtration gravel, the company built a new center in the Syski area, about 5 km from the Grudzen Las sand quarry. The company’s philosophy has evolved over time into its present form, when Grudzeń Las Sp. successfully certified its processes in 2005. In addition to the above listed products, the company produces filtration gravels, technical sands, kaolin, silica and dolomite flours. Physical and chemical monitoring highly contribute to the quality assurance of all products. New equipment and the latest machinery contribute to achieving these requirements. The company’s objective is to produce moulding and glass sands of the highest quality. z o.o.” began its independent activity on 1 June, 1988. The company “ Kopalnia Piasku Kwarcowego Grudzeń Las Sp. Requirements of the heavy industry on sand quality in the 1970s contributed to the introduction of hydraulic classification based on the Austrian technology that was implemented at the “Grudzeń Las” silica sand plant in 1974. At first, these sands were used in the foundry industry in their raw state. The Grudzeń Las site started to be exploited in the 1930s.
Sands from this area were first used in the late 19th century. The Grudzeń Las sand plant exploits two deposits - “Grudzeń Las” and “Piaskownice Zajaczków Wschód” located in the Tomaszow valley.
