Unlike green sand, chemically bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets it`s strength through chemical reaction which is irreversible in nature. Each sand particle is coated with this reacted chemical, which behaves like an inert element after usage once. This inert coating also called “Dead” binder needs to be removed from the us...

Abstract West Sumatra has the potential of abundant natural resources in form iron sand, one which is located Pasia Jambak Beach area, Nan Tigo, Padang. Basically sands have magnetite ( Fe 3 O 4 ), hematite α-Fe 2 and maghemite γ-Fe ) can be used as a mineral high economic value. However, sand Beach, no known magnetic mineral. This study aims to investigate content Padang based on its susceptib...

This work aimed to synthesize MnFe2O4 nanoparticles using the coprecipitation method. Manganese chloride dihydrate (MnCl2.4H2O) and iron sand from South Cianjur, Indonesia, were used as a precursor for nanoparticle synthesis. The elements compounds tested X-Ray Fluorescence (XRF). was characterized Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive (SEM-EDX), Vector Network Analy...

Abstract A study was carried out on the mineral composition and free Iron oxides of sediments Tigris Euphrates river. Two soils were selected representing (Al-Numaniyah) river (Al-Shamiya), physical chemical analyzes conducted them, sand is separated by means a sieve whose openings are (53 microns) in presence absence into separations (53-2000) micrometers, to prepare them for metallurgical exa...

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we face today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposit...

We present an interactive sand art drawing system using one RGB-D sensor, such as Kinect. Our system supports the common sand drawing functions, such as sand erosion, sand spilling, and sand leaking. To use hands to draw virtual sand on a drawing plane, we design four key gestures which enable drawing manipulation actions for sand. The basic idea is that the gesture of one hand controls the dra...
