[Sebagian besar produksi nikel dunia bersumber dari bijih sulfida, sebaliknya sebagian besar sumber cadangan nikel dunia dikuasai bijih laterit. Kedepannya, produksi nikel yang bersumber dari bijih laterit sangat dibutuhkan untuk memenuhi kebutuhan nikel dunia karena cadangan nikel yang bersumber dari bijih sulfida sudah mulai menipis. Metode pelindian asam (acidic leaching) biasa digunakan untuk memproduksi nikel murni, dimana umumnya asam sulfat digunakan sebagai media pelindian. Akan tetapi, penggunaan asam sulfat di dalam metode acidic leaching memiliki ...

This study was aimed to
determine the reaction stoichiometry between Cu(II) and di-2-ethylhexylphosphoric
acid (D2EHPA) in Waste Palm Cooking
Oil (WPCO). The stoichiometry was computed based on
the following
experimental
methods, namely slope analysis, loading test and Job?s
method. Slope analysis was used to measure the variation of the distribution coefficien ...

This study was aimed to determine the reaction stoichiometry between Cu(II) and di-2-ethylhexylphosphoric acid (D2EHPA) in Waste Palm Cooking Oil (WPCO). The stoichiometry was computed based on the following experimental methods, namely slope analysis, loading test and Job’s method. Slope analysis was used to measure the variation of the distribution coefficient D to the concentration of Cu(II) ions and D2EHPA. Besides that, the loading test and Job’s method are used to determine and confirm the ...
