Determination of tin in cassiterite ores and tailings by ...

1997-1-1  A rapid and precise method was used for the determination of tin in cassiterite ore and tailings from the tin province of Jos Plateau, Nigeria using 241 Am isotopic X-ray source. The application of the method is very attractive when compared to solution methods of analysis. Concentration of the ore samples vary from 60 to 78% while the tailings ...

Concentration of Ores eMedicalPrep

Hydraulic washing is used for ores that have tin or lead, as they are heavier than the gangue. Fig. 1. Hydraulic washing. Magnetic Separation. It is based on the principle of magnetic properties of the ore components. If either the ore particles or the gangue are capable of being attracted in a magnetic field, magnetic separation can be used.

Tin processing Britannica

2020-8-17  Tin processing, preparation of the ore for use in various products. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is allotropic; that is, it takes on more than one form.
