In 2021, China imported 3.4547 million tons of quartz sand, and the average import price was 320.13 yuan / ton; The export of quartz sand was 82,900 tons, and the average export price was 115.25 yuan / ton. In 2020, China’s quartz sand imports will be 3.3454 million tons, and the average import price will be 285.78 yuan / ton. Compared with 2020, China’s quartz sand imports will increase in 2021.
In recent years, due to the increase in demand, the price of various types of quartz sand (rock) has risen all the way, whether it is quartz sand for foundry, quartz sand for fracturing, quartzite for metallurgy, quartz sand for ordinary glass, quartz sand for photovoltaics, quartz sand for plates and high-purity quartz, etc., the price has risen sharply. Hainan is an important quartz sand producing area in China, in recent years, the price of all kinds of quartz sand has risen sharply, such as the price of machined quartz sand is 100~110 yuan / t, the price of quartz sand for float glass is 150 ~ 160 yuan / t, and the price of quartz sand for photovoltaics is 260 ~ 280 yuan / t. In Gansu, even the price of quartzite for metallurgy has reached 70~80 yuan / t. In 2020, the market size of quartz materials in China has reached 20 billion yuan.
Quartz sand is an important industrial mineral raw material, which can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand and fused silica sand according to quality. General industrial quartz sand is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries. With the rise and development of strategic emerging industries, the industrial application of quartz greatly exceeds the traditional application range. High-purity, high-performance quartz has become an indispensable material in electronic information, semiconductor, optical light source, photovoltaic energy, aerospace and other fields. In this regard, in recent years, the overall industrial chain of quartz sand has attracted much attention, the market is extremely hot, and the demand is growing rapidly.
