Nickel lateritic ores have high moisture contents as well as chemically bonded water in the hydroxide form. Dehydration is a minimum and some pre-reduction of the ore in a rotary kiln is used to optimize the utilization of electric power for smelting operations in the electric arc furnace. Ferronickel production therefore typically uses a rotary kiln and electric furnace process. After the saprolitic ore has been sized for treatment and partially dried‚ it is fed together with a solid reductant to

Various sources define visible light as narrowly as 420 to 680[4][5] to as broadly as 380 to 800 nm.[6][7] Under ideal laboratory conditions‚ people can see infrared up to at least 1050 nm‚[8] children and

Many scientific‚ military‚ medical and commercial laser applications have been developed since the invention of the laser in the 1958. The coherency‚ high monochromaticity‚ and ability to reach extremely high powers are all properties which allow for these specialized applications. Scientific In science‚ lasers are used in many ways‚ including: A wide variety of interferometric techniques Raman spectroscopy Laser induced breakdown spectroscopy Atmospheric remote sensing Investigating nonlinear

Transmission media lie below the physical layer. We can evaluate transmission media by throughput‚ propagation speed‚ and propagation time. * A guided medium provides a physical conduit from one device to another. Twisted-pair cable‚ coaxial cable‚ and optical fiber are the most popular types of guided media. Twisted-pair cable consists of two insulated copper wires twisted together. Twisting allows each wire to have approximately the same noise environment. Twisted-pair cable is used in

Abstract: The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however‚ product of the first step‚ Benzoin‚ is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment‚ the microscale techniques of reflux‚ crystallization‚ and melting-point determination were used. Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained‚ as well as
