High purity zircon ZrSiO 4 nanopowder was successfully produced from Indonesian natural zircon sand using a low cost purification approach via magnetic separation immersion in HCl and reaction with NaOH followed by a top down nanosizing process using wet ball milling for 10 h and annealing at 200 °C for 2 h Furthermore polymorph zirconia ZrO 2
In 2022 the total volume of silica sand produced in Indonesia was estimated to amount to approximately million cubic meters
Characterization of Post Mining Soil and Solid Waste the concentration and structure of silica are dif ferent in each country Open pit silica mining in the Tuban Regency Indonesia has demonstrated a topsoil stripping technique for further explora tion of the subgrade containing silica sand Gen erally it has quartz sand and clay so that silica sand purification is required to obtain
According to the regulatory requirements of soil quality standards in Indonesia long term exposure to heavy metals through the air water soil This is due to the silica sand purification process using the water dispersion method so that the solid waste has a high water content Fig 1 This condition also affects the permeability

Solid waste was obtained from the silica sand refining industry in Jenu Village Jenu District Tuban Regency East Java Indonesia located at 6°50′″ South Latitude 112°00′″ East Longitude with an altitude of 10 m above sea level Sampling was carried out randomly on disturbed soil
According to the regulatory requirements of soil quality standards in Indonesia long term exposure to heavy metals through the air water soil This is due to the silica sand purification process using the water dispersion method so that the solid waste has a high water content Fig 1 This condition also affects the permeability
Indonesia has very abundant reserves of silica but progressive studies on the deposition of this material are very few resulting in limited applications of silica This work refers to the purification of silica from quartz sand originated from Sukabumi Indonesia to obtain high purity silica which can be applied as important raw materials
Iron is a major impurity in quartz sand and must be strictly removed in many applications However the iron removal rate in most of the conventional purification process is not high enough In this study a fast low energy consuming environment friendly and simple process for purifying quartz is demonstrated by a combination of microwave heating and
The global silica sand market size reached US$ Billion in 2023 As per the analysis by IMARC Group the top silica sand companies are focusing on product enhancement and innovations to widen their offerings catering to a rapidly growing customer base worldwide Moreover the leading manufacturers are utilizing low grade silica sand to introduce novel
To obtain high purity silica sands by using quartz vein ore from Dabie Mountain Anhui province China as raw material this study investigated a quartz purification process that involves
The natural silica sands from Bancar and Tanah Laut were first purified There was a gradually steps for purification of the sands cleaning & sieving magnetic separation milling another magnetic separation and soaking with hydrochloric acid prior to a hydrothermal treatment The previous steps would produce cleaned sands which were ready
of power ultrasound to the surface cleaning of silica [11] acid leaching [12 13] and reverse flotation technique [14] 2 Experimental procedure The silica used in this work is a natural one from the region of Siliana in Tunisia In first time of purification a silica was dipped for a few minutes in an acids mixture solution HCl HNO 3 with
