Quartz is a silicate mineral with a shelf-like structure and is the main mineral component of quartzite and quartz sand. Its colour is milky white or colourless in a translucent state and its Mohs hardness is 7-7.5. In addition, quartz is chemically stable, insoluble in acids (except HF) and slightly soluble in KOH solutions.Metallurgical grade silica is required for solar panels and mining companies have discovered WA's South West region could have vast deposits of the mineral.Silica mining exploration in WA's South West prompts fears for

A Life Cycle Assessment of Silica Sand: Comparing the MDPI
Silica sand or quartz sand is a mineral resource with a wide variety of application; glass industry, construction and foundry are the most common examples thereof. The Republic of Croatia has reserves of 40 million tons of silica sand and a long tradition of surface mining and processing. The average annual production of raw silica Heavy mineral sands are the source of various commodities such as white titanium dioxide pigment and titanium metal. The three case studies in this paper show the value of X-ray diffraction (XRD) and statistical methods such as data clustering for process optimization and quality control during heavy mineral processing.
