The titanium produced by the Hunter process is in the form of powder called sponge fines. This form is useful as a raw material in powder metallurgy. The main limiting factor for the usefulness of the Hunter process is the difficulty of separating the produced NaCl from the titanium.
A stream of titanium tetrachloride gas is added to a stream of molten sodium; the products (sodium chloride salt and titanium particles) is filtered from the extra sodium. Titanium is then separated from the salt by water washing. Both sodium and chlorine are recycled to produce and process more titanium tetrachloride. [78]
Far Lands or Bust (abbreviated FLoB) is an online video series created by Kurt J. Mac in which he plays the video game Minecraft.The series depicts his journey to the "Far Lands", a distant area of a Minecraft world in which the terrain generation does not function correctly, creating a warped landscape.
Liquation is a metallurgical method for separating metals from an ore or alloy.The material must be heated until one of the metals starts to melt and drain away from the other and can be collected.
The basic process involved the mixing of argentiferous gold foil (in later periods granules were used), common salt and brick dust or burnt clay in a closed and sealed container. Theophilus mentions the addition of urine to the mix. With heating, the silver reacts with the salt to form silver chloride which is removed leaving a purified gold ...
Metal laboratory sieves An ami shakushi, a Japanese ladle or scoop that may be used to remove small drops of batter during the frying of tempura ancient sieve. A sieve, fine mesh strainer, or sift is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet ...
The second step, once the diastereomers have formed, is to separate them using recrystallisation. This is possible because enantiomers have shared physical properties such as melting point and boiling point , but diastereomers have different chemical properties, so they can be separated like any two different molecules.
Lead is a common metal, but its discovery had relatively little impact in the ancient world. It is too soft to use for structural elements or weapons, though its high density relative to other metals makes it ideal for sling projectiles.
