Effluent and sediment samples were collected on seasonal basis, comprising of three months (August to October) in the wet season and three months (December to February) in the dry season from five points around a lubricating oil company in Osogbo - Nigeria. The sequential extraction method was used to respectively fractionate the sediment and effluent samples, then analyzed by Atomic

Africa is a gold mine, literally. The continent exports tens of billions of dollars worth of the precious metal annually from 46 countries, and much of the activity is legal.
The study found that producing battery metals from nodules can reduce active human emissions of CO 2 e by 70-75%, stored carbon at risk by 94% and disruption of carbon sequestration services by 88%." • Read more about deep sea mining here.
Mining is the extraction[removal]of minerals and metals from the earth. The Nigerian Coal Corporation (NCC) is a parastatal corporation that was formed in 1950 and held a monopoly on the mining, processing, and sales of coal, lignite, and coke products until 1999.. Coal was first discovered in Enugu in 1909 at the Udi Ridge in Enugu,This was found by a British mine Engineer known as Albert Kitson.
Team extracting precious metals from e-waste using fruit peels Marie Donlon | August 26, 2020 A team of scientists from the Nanyang Technological University, Singapore (NTU Singapore), has devised a method for extracting and reusing precious metals from depleted lithium ion batteries using fruit peels.
04.11.2019· Overview. A new World Bank Group report, "Minerals for Climate Action: "The Mineral Intensity of the Clean Energy Transition," finds that the production of minerals, such as graphite, lithium and cobalt, could increase by nearly 500% by 2050, to meet the growing demand for clean energy technologies. It estimates that over 3 billion tons of minerals and metals will be needed to deploy wind
Etymology and pronunciation. Metallurgy derives from the Ancient Greek μεταλλουργός, metallourgós, "worker in metal", from μέταλλον, métallon, "mine, metal" + ἔργον, érgon, "work".. The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense

The fractionation of heavy metals in riverbed sediments along the Tietê River basin, a highly polluted river in southeast region of Brazil, was investigated using a four-step sequential extraction procedure, in order to determine the concentration and distribution of Cu, Co, Cr, Cd, Zn, Ni and Pb, in the river bottom sediments, related to the potential mobility of geochemical phases.
Using their SAC method, ethanol extraction was almost total with a reduction from 66 % of the total volume to between 5.4–26 % in the RF. The researchers analyzed the lignan data, constructing regression models, and found that optimal extraction occurred with 180 minutes of treatment time, an operating pressure of 30 MPa and with a CO 2 flow rate of 15 kg h -1 .
Dans le cadre du projet de réactivation de l'exploitation de la mine de fer de Bandjéli, le Togo envisage l'extraction de 100 mille tonnes de fer par an. Cette mine regorge de 1 milliard de tonnes de gisement de fer. Le projet a pour but, de faciliter un schéma de partenariat public-privé en vue de []
The metal removal rates varied from rapid removal for Cu to slower rates of removal for Co and Sr. The resuspension event did not trigger any increase in dissolved Cu, Co, or Sr. Additional 96‐h experiments were conducted using dissolved Ni, Pb, Zn, and Ag and supported the conclusion that the T/DP‐E is sufficiently robust to distinguish removal rates between metals with a wide range of

Bassar as-smelted Steel is steel made by direct reduction of Bandjeli iron ore in a natural draught furnace. Bandjeli village is located in the Bassar Region in the Republic of Togo (West Africa). The Bassar remelted steel was obtained by melting at 1370°C of Bassar as-smelted Steel in a high frequency furnace to eliminate inclusions and pores contained in the Bassar as-smelted Steel.

Now, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste. One example reported in Rapaport Magazine describes the efforts of De Beers Consolidated Mines (DBCM) to extract overlooked diamonds from 360 million tons of old tailings surrounding the Kimberley mines in South Africa.
