Solid pollution has been an issue in mineral processing for decade. One of these pollutants is zircon sand mining waste (zircon tailing). Due to the concentration of rare earth minerals in zircon tailing and the increasing demand of REE in advanced technologies, studying zircon tailing as a potential source of REE had become an interest for us.
The largest composition of these sand deposits is found mostly in the Northern regions of Nigeria. The zircon sand is produced as a byproduct of the tin mining process [9,10,11,12]. Prior research on Nigerian zircon sand centered on its application as foundry sand, refractory material, and composite analysis.
Zircon is also supplied as a lower-grade concentrate, e.g. from Southeast Asia (Indonesia and Vietnam), with zircon content ranging from 65% to 85% (average 75%). Most zircon concentrate is supplied to China for further processing. …
Heavy surface mineralisation occurs in the sand units near Namalope flats and Tupuito high dune areas. The HM sand deposits occur in a sequence of fine to medium grained and silty sands consociated with clay units. The mineralisation constitutes about 85% of ilmenite, 5% of zircon and 2% of rutile, with minute variations among the units.
The processing and validation of the zircon sand concentrate process into the zircon opacifier have been carried out. The purpose of this research was to determine the optimal processing conditions and the process validation parameters, namely the production repeatability, and product consistency.

Murray Zircon took over the site in 2011 after the previous operator, Australian Zircon, went into voluntary administration. Murray Zircon successfully completed rehabilitation of the project's Mindarie A2 strandline in 2011 and commenced mining the project's Mindarie C strandline from 2012-2015, producing a heavy mineral concentrate (HMC).
Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals. The major end uses of zircon are refractories, foundry sands (including investment casting), and ceramic opacification.
Therefore it is necessary to conduct an assessment the potential reserves related to the source material contained in the zircon sand and radiation safety that are applied in the process of mining or processing of zircon sand. In this paper the location of mining and processing of zircon sand is restricted to the province of Central Kalimantan.

Murray Zircon Pty Ltd is a mineral sands mining company focused on the production of heavy mineral concentrate (HMC) in the Murray Basin in South Australia. The Company was formed in June 2011. Murray Zircon's principal asset is the Mindarie Mineral Sands Project, located 150km east of Adelaide in the Mallee region of South Australia.
The process usually involves: 1. Wet Gravity Concentration: This process separates the heavy minerals based on their specific gravity. The sand is mixed with water to create a slurry, which is then passed through spiral concentrators. The heavier minerals, including zircon, sink to the bottom and are collected. 2.
In the beginning of 2008, we started solely with the mining and purification of zircon sand to its purity content of 65 % minimum.

Zircon beneficiation processing methods are often divided into wet and dry type processes. The raw ore is first treated with wet type processing, and the gangue minerals such as quartz, feldspar and mica are removed by gravity separation equipment such as cone concentrator, spiral concentrator, shaker table or mineral jig.
