  1. Separating Mixtures By Jason

  2. Filtering and Sieving • Filtration only allows smaller particles than the designated area to flow through to the next layer causing oversized particles to stop and not make it through to the next layer. • Sieving only has one layer allowing only designated sizes to get through and therefore not being so accurate.

  3. Sedimentation • Sedimentation can be a form of rock that has taken many years to form. It is created when a lake dries up over time and all the sediment start to fall and hit more layers creating a very thin and layered rock that can withstand a lot of pressure. • Another way sediment is formed is after a lake has dried up it gets a lot of pressure causing layers to form.

  4. Flotation • Flotation is a way of separating two or more materials from each other. One way of doing this is filling a cylinder with water (or a designated liquid) and allowing the heavy materials to fall to the bottom and the lighter materials to float on the surface and which ever material is needed can then be collected. This sort of separation is mainly used in the mining industry.

  5. Chromatography • This is a type of separation where materials are pushed through pipes at increasing speeds and slowly the more dense materials will fall back leaving only the fastest materials to get to the end first.

  6. Adsorption • Adsorption is a type of way to separate separate mixtures. It is done by collecting a piece of material that absorbs a type of material like a sponge. The sponge absorb liquids meaning that if you want to separate a solid like sand from a liquid like water you can place the sponge in the water and only the sand will be left.

  7. Electrostatics • Electrostatics is almost like a magnet. An example would be when you have static on a balloon and pass the balloon over your head, your hair floats up almost as if it were a magnet. In this sort of way it is possible to sort heavy items from light materials that would be able to be sorted.

  8. Large SCALE SEPARATING MIXTURES • One of the big large scale separating mixtures examples, is the mining industry. They use the froth method to separate lighter minerals from heavier minerals. • Yet another large scale operating system would be the farming industry. They use a way of filtering the right fruit from the fruit that is a bit bruised or discoloured. • Another main large scale operating system would be chemistry industry. They make most medicines by using most of the methods that are covered.
