It makes he paper white by bleaching it! :D
The raw materials needed for making iron are iron ore, coke (a type of coal), and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities during the smelting process.
limestone blocks ;0)
Limestone is used in paper production as a filler material to improve the paper's smoothness, brightness, opacity, and bulk. It helps to enhance the paper's printability and reduces production costs by replacing more expensive materials. Additionally, limestone also helps to neutralize acidic impurities in the paper, improving its longevity and stability.
Limestone
actually, limestone is used in making concrete, not the other way around.
The pulp industry uses lime in various stages of the production process:in chemical pulp production, sodium carbonate is treated with lime to regenerate the caustic soda;in the sulphate process, lime is used to produce a calcium bisulphate liquor capable of dissolving non-cellulose wood elements;lime is used as a bleaching agent for pulp, as well as a flocculating, neutralising and clarifying agent for residual water.
Limestone is made up of calcium oxide which is the key ingredient to make cement. The limestone is mixed in with a particular clay to get the cement mixture.
Limestone is refined to make portland cement.

we wouldn't have these- -Limestone is used in buildings and roads. - Limestone can be used in glass making. - Limestone is used in toothpaste. - Limestone is used in cement and mortar. - Limestone is used in bread and cereals as a source of calcium. - Limestone is used to make paper white. -Limestone is used to purify sugar. -Pulverized limestone is used to neutralize acidic soils. -Limestone can be used to make brake pads. -Limestone is used in the preparation of wools and dyes. -Limestone is used to make antacids. -Limestone is used in climbing walls. -Limestone is used a suppression of methane explosions in underground coalmines. -Limestone is added to plastics, paint, tiles and other materials as both white pigment and cheap filler. -Limestone is used in the manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide). -Limestone can be used to create steel by using it in a blast furnace.
True. Vinegar contains acetic acid which can dissolve the calcium carbonate in limestone, making it possible to separate the fossils from the limestone.
For bookbinding projects, the best type of paper cutter to use is a guillotine cutter. It provides clean and precise cuts, making it ideal for trimming paper to the exact size needed for binding.
