a diaphragm compressor also known as a membrane compressor is a variant of the conventional reciprocating compressor. the compression of gas occurs by the movement of a flexible membrane, instead of an intake element. the back and forth movement of the membrane is driven by a rod and a crankshaft mechanism. only the membrane and the .
the first pair of electromagnets was weakly magnetised and served to d off any iron ore present. the second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. these machines were capable of treating 10 tons of ore a day. this process of separating magnetic substances from the non-magnetic substances in a mixture with the help of a magnet is called magnetic separation.. this process operates by moving particles in a magnetic field.
heckling or 'hackling' is the last of three steps in dressing flax, or preparing the fibers to be spun. it splits and strhtens the flax fibers, as well as removes the fibrous core and impurities. flax is pulled through heckling combs, which parts the locked fibers and makes them strht, clean, and ready to spin.
a 'refractory' gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. these ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. these refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold.
the history of electromagnetic theory begins with ancient measures to understand atmospheric electricity, in particular lightning. people then had little understanding of electricity, and were unable to explain the phenomena. scientific understanding into the nature of electricity grew throughout the eighteenth and nineteenth centuries through the work of researchers such as coulomb, ampère .
