Selective Water Leaching of Sulfated Rare Earth Ore and Impurity Removal from a Rare Earth Sulfuric Liquor

Autor: Eder Domingos de Oliveira, Carlos Antonio Morais, Ruberlan Gomes Silva

Publikováno v: Mining, Metallurgy & Exploration. 37:519-535

The objective of this work was to assess the influence of parameters such as residence time, solid content, and temperature in a process route towards purified rare earth liquor which could be adequate to produce marketable rare earth products. The s

Evaluation of Different Neutralization Reagents in the Selective Removal of Impurities in Rare Earth Sulfuric Liquor

Autor: Ruberlan Gomes Silva, Carlos Antonio Morais, Eder Domingos de Oliveira

Publikováno v: Mining, Metallurgy & Exploration. 37:65-78

The objective of this study is to assess the impact of different reagents, such as limestone, lime, magnesium oxide, and sodium hydroxide, in experiments carried out in the single purification step and in two consecutive purification steps by raising

Selective precipitation of rare earth from non-purified and purified sulfate liquors using sodium sulfate and disodium hydrogen phosphate

Autor: Carlos Morais, Eder Domingos de Oliveira, Ruberlan Gomes Silva

Publikováno v: Minerals Engineering. 134:402-416

The conventional hydrometallurgical process routes for the recovery of rare earth elements (REEs) from ores employs sulfuric acid. After being leached, the rare earth sulfate liquor presents impurities that need to be removed before they can be used

Selective Extraction of Rare Earth Elements from Monazite Ores with High Iron Content

Autor: Ruberlan Gomes Silva, Virginia S.T. Ciminelli, Leandro Augusto Viana Teixeira, D. Majuste, Angela Nair Avelar

Publikováno v: Mining, Metallurgy & Exploration. 36:235-244

Rare earth elements are essential for modern life products and green technologies. Recent supply constraints have boosted the development of rare earth projects after the price peak of 2011. The feasibility of a project depends on the definition of a

Enhanced process route to produce magnetite pellet feed from copper tailing

Autor: Matheus Bianchetti, Thiago Cesar Souza, Ruberlan Gomes Silva, Lucas Reis, José Maria Silva, Lorena Abdalla de Oliveira Prata Guimarães, Eugênio Oliveira

Publikováno v: Minerals Engineering. 173:107195

The majority of copper mines generate a large quantity of tailings after their concentration processing. The flotation tailings are, in general, either piled up or stored in dams, although most copper tailings have a huge potential for by-products pr

Enhanced process route to remove fluorine and uranium from copper concentrades by selective sulfuric acid leaching

Autor: Ruberlan Gomes Silva, Lorena Abdalla de Oliveira Prata Guimarães, Danielly Couto, Aline Cristina Tavares

Publikováno v: Minerals Engineering. 170:107039

The main Cu-bearing mineral in copper concentrates consumed in smelters around the world is chalcopyrite (CuFeS2). Minor participation in this consumption is copper concentrates containing secondary copper minerals, such as chalcocite (Cu2S) and born
