The embodiments of this invention which are claimed are as follows 1. A process for the recovery of metal values from ocean floor nodule ore the ore comprising as primary components compounds of copper cobalt and nickel; the process comprising the steps of 1 reacting the nodule ore with a halide reactant comprising at least one halide of a metal selected from the group consisting of the .
The embodiments of this invention which are claimed as follows 1. A process for the recovery of pure metal halides from ocean floor nodule ore the ore comprising as major components the oxides of manganese and iron and as secondary components compounds of copper cobalt and nickel the weight ratio of manganese-to-nickel-plus cobalt being at least about 9 the process comprising the steps .
A method is disclosed for recovering and separating precious and non-precious metals from waste streams which removes separates and recovers such metals in a cost effective manner with more than 95 removal from waste streams and with minimal amounts of unprocessed solids and sludge remaining in the environment. Metals such as chromium manganese cobalt nickel copper zinc silver gold .
Jun 08 2021 API has determined that most sludge settles out of the production stream and remains in the oil stock and water storage tanks. Like contaminated scale sludge contains more Ra-226 than Ra-228. The average concentration of radium in sludges is estimated to be 2.775 Bqg 75 pCig. This may vary considerably from site to site.
Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed these rocks expose radioactive elements asbestos-like minerals and metallic dust. During separation residual rock slurries which are mixtures of pulverized rock and .

Direct a forceful stream of water at the earth and it will carve a ditch and carry away the loosened soil. Inquire Now; Whats the science on deepsea mining for rare metals . Deepsea mining presents an advantage on that score as the oceanbased resources would be harvested by remotelycontrolled machines that suck up . Inquire Now
This bleed stream is then further treated typically by neutralization to precipitate the contained metals. Nickel can be recovered from the bleed stream of a copper electrorefinery. Classical methods for nickel recovery are precipitation oxidation and crystallization.
Feb 21 2019 Mining activities including prospecting exploration construction operation maintenance expansion abandonment decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative and direct and indirect ways. Mining can yield a range of benefits to societies but it may also cause conflict not least in relation to above
