flow diagram is a graphic representation of the physical route or flow of people, materials, paperworks, vehicles, or communication associated with a process, procedure plan, or investigation. in the second definition the meaning is limited to the representation of the physical route or flow. an example of such a diagram is the illustration .
mannitol is commonly used in the circuit prime of a heart lung machine during cardiopulmonary bypass. the presence of mannitol preserves renal function during the times of low blood flow and pressure, while the patient is on bypass.
prospecting is the first stage of the geological analysis of a territory. it is the search for minerals, fossils, precious metals or mineral specimens, and is also known as fossicking. traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. once an anomaly has been identified and interpreted to be a p
ray kurzweil is known for taking over 200 pills a day, meant to reprogram his biochemistry. this, according to kurzweil, is only a precursor to the devices at the nano scale that will eventually replace a blood-cell, self updating of specific pathogens to improve the immune system.
ultimate recovery of the target mineral can range from 30% of contained run-of-mine dump leaching sulfide copper ores to over 90% for the ores that are easiest to leach, some oxide gold ores. the essential questions to address during the process of the heap leaching are as following:
flow rates can be increased to separate higher size ranges. further size fractions may be collected if the overflow from the first tube is passed vertically upwards through a second tube of greater cross-section, and any number of such tubes can be arranged in series. it is used in mineral processing for size classification. the elutriation .
mintek is south africa's national research and development r&d organisation for all aspects of mineral processing, extractive metallurgy and related technology. originally established as a minerals research laboratory by the government of south africa in 1934, it is still partly funded by the state with a mandate to 'promote mineral technology and to foster the establishment and expansion of .
a slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances.a mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out.due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene hdpe , or manufactured .
