“…A weight 10 g of Egyptian cassiterite collected from Rasheid factory of black sand was ground to 0.297 mm and treated with 100 mL of 3 mol L −1 hydrochloric acid and stirred for 48 h at 100-110 °C in atmospheric conditions. After filtration, the cassiterite residue left over the filter paper was washed carefully several times with distilled water to remove any traces of chloride impurities and then dried at 100 °C for 2 h [8]. The chemical analysis of the purified cassiterite represents in Table 1 according to Abdel-Aal and Abdel-Hay [9].…”

This work concerned with the extraction of Th(IV) from aqueous solutions using natural cassitrite adsorbent natural tin oxide mineral (SnO 2 ). The achieved maximum Th(IV) adsorption efficiency (99.2%) depends mainly on some effective parameters such as pH value, contact time, dose of cassiterite, concentration of Th(IV) and temperature. The Langmuir and Freundlich models are used to simulate the sorption isotherms, respectively. On the other hand, not less than 99.6% of the uptaken Th(IV) was regenerated using 0.005 mol L −1 HCl solution by stirring for 25 min to yeild Th(IV) concentrated solution. The concentrations of Th(IV) in all extraction process were spectrophotometric estimated using 1,4-di-hydroxy anthraquinone and Arsenazo(III) at λ max 600 and 655 nm, respectively.

“…Firdiyono et al (2018) melarutkan elemen Ce, Nd, Y dan La dari kasiterit menggunakan pelarut asam klorida, asama sulfat dan sodium hidroksida. Elemen tersebut adalah penyusun mineral monazit yang merupakan mineral ikutan dalam kasiterit [8]. Peng et al (2017) mencoba memisahkan mineral ikutan zirkon dari kasiterit dengan teknik flotasi menggunakan reagen sodium oleat [9].…”

Abstrak: Telah dilakukan penelitian kelarutan mineral ikutan kasiterit (SnO2) dalam larutan asam klorida (HCl) encer menggunakan reaktor yang dilengkapi pengaduk. Tujuan penelitian adalah melakukan investigasi dalam upaya memperoleh kondisi proses yang optimum dan efisien, khususnya temperature dan waktu proses pelindian untuk menghasilkan kasiterit dengan kemurnian tinggi. Proses yang dilakukan adalah hidrometalurgi dengan melakukan proses pelindian mineral kasiterit dalam larutan HCl 10% (encer) pada kondisi tekanan atmosferik dan variasi temperatur 35°C, 50°C, 70°C, 90°C, 110°C; waktu proses 1, 2, 3, 4, 5, dan 6 jam. Proses pelindian menggunakan reaktor yang dilengkapi pengaduk dengan pengadukkan 300 rpm. Hasil penelitian menunjukkan larutan asam klorida (HCl) 10% mampu melarutkan mineral ikutan dari kasiterit diantaranya: besi, lantanum, cerium, titanium yang merupakan pengotor dengan jumlah besar dalam kasiterit. Kemurnian kasiterit yang diperoleh dari hasil pelindian menggunakan larutan HCl 10% (encer) adalah sebesar 82-83% SnO2 pada temperatur 110 oC selama 2 jam.Kata kunci: kasiterit, mineral ikutan, asam klorida, reaktor berpengaduk, pelindian
