“…Granulation and atomization of metal is still a challenging task, in which metal lumps and scrap are converted into fine grains of required size. 1–3 Gas atomization is one of the methods used to get fine powder from metals. 3–6 In granshot process, the metal is converted into granules by simple processing using a continuous casting machine with some modifications.…”

Metal granshot is a process that is used to convert metal lumps or scraps into metal grains of uniform sizes and shapes. The concept of metal granulation is based on the heat difference between melting and pouring medium. The commercial uses of metal granules are jewelry making and spray coating of costly metals such as silver, gold, and platinum. The basic aim of the silver granshot process is to get uniform size, shape, and maximum yield of silver metal granules. During processing, the metal gets superheated within vacuum up to viscosity more than 2.2 cP flow out of the minimum diameter orifice and allow to drop in the coolant with high pressurized argon gas. The present study focuses on the granulation of silver and tries to achieve the maximum yield of metal. The shape and size of the granules produced were observed using scanning electron microscopy and the results show that the average diameters of granules are between 1.2 mm and 3.8 mm. Yield is also considered as an important factor for granulation of valuable metals like silver, and after experimentation successfully achieved the 99.9 percent yield. The granulation process of silver will help to ease the trading of metal in the jewelry industry.

Removal of thorium ions from acidic media using high effective bio-adsorbent is a very convenient viewpoint for the management of environmental pollutants. With this respect, this study is aimed to synthesize bio-adsorbent derived from date palm seed (DS bio-adsorbent) for adsorption of Th(IV) from acidic media. The studied bio-adsorbent was characterized by FTIR, SEM, and XRD techniques. The effective experimental parameters on the adsorption performance such as pH, bio-adsorbent dose, contact time, solution temperature, thorium initial concentration, and interfering ions were investigated. Furthermore, adsorption isotherm and kinetic studies were explored to describe the mechanism of thorium adsorption using the proposed bio-adsorbent. The Langmuir model result showed that the DS removal adsorption capacity was 43 mg.g-1 at optimized batch conditions. The kinetic findings indicated that the adsorption mechanism was in an agreement with the pseudo-second-order model. Additionally, the regeneration of the spent bio-adsorbent was studied using 0.3 mol.L-1 HNO3 as an eluent agent. This research suggested that the date palm seed bio-adsorbent could be evaluated as a beneficial adsorbent for the adsorption of thorium from aquatic and acidic media due to its selectivity and capacity.
