Sand and Limestone form the base raw materials towards producing glass. It’s major characteristics of being natural and stable mineral in nature helps glasses maintain a low rate of chemical interaction.

Glass containers are 100% recyclable, without having to lose its purity and degrading its quality. This recycled glass further helps in saving more than a ton of the raw materials required to create new glass. Also, recovered glass from glass recycling is the primary ingredient in all new glass containers. There are multiple processes involved in glass manufacturing. One such procedure is the Sand Beneficiation.

Sand Beneficiation is nothing but a process that primarily involves all the resizing work and removing impurities.

Every manufacturing process involves resizing or reshaping or removal of things. Sand Beneficiation process does exactly that! It is nothing but a process that primarily involves all the resizing work and removing impurities. The resizing process of Sand Beneficiation involves - crushing or grinding, screening and centrifugation, sintering, palletizing. Removal of impurities process of Sand Beneficiation involves - washing, flotation, leaching, filtration, dissolution, drying, roasting etc.

This is one of the most important procedures of glass manufacturing. Sand Beneficiation Plant has become one of the important requirements of manufacturing, with the massive expansion of glass industry.

Out of the several plants of HNG, Sand Beneficiation is carried out at our plants at Naidupeta and Puducherry.
