The use of diphenylthiourea in conjunction with potassium iodide or tin(II) chloride provides a systematic scheme for the extraction—separation of platinum, palladium, rhodium, iridium, and gold in hydrochloric acid solution
In this paper, we report the solvent extraction separation and recovery of palladium (Pd) and platinum (Pt) from hydrochloric acid leach liquors of spent automobile catalyst employing precipitation and solvent extraction methods
Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another This is known as the flotation separation method, and produces a frothy layer of particles that can be .
Extracting platinum from ore is both capital and labor intensive It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31135g) of pure platinum The first step in this process is to crush platinum containing ore and immerse it in the reagent ,
that underlie this method of separation The platinum group metals platinum, palladium, rhodium, iridium, osmium and , Amine solvents can be used for the extraction of platinum and iridium The structure of some commercially available extractants in each class is given in Table 11

Definition of platinum extraction conditions are based on diagrams showed on fig1 Concentration of extracted platinum by solvent extraction from rhodium acid solution was Pt
Extracting Platinum from these ores is arguably one of the most capital and labour intensive operations in the world On average, it takes up to six months and up to 12 tonnes of ore to produce an industry standard troy ounce, which is 31135 grams of pure metal
Platinum platinum mining and extraction methods The mining of platinum ores is similar to gold mining inasmuch as the orebody is a thin, tabular reef covering an extensive area
