The use of zeolitebased geopolymers as adsorbent for copper .
The solution was mixed with zeolite at a ratio of mL g1and stirred for 2 minutes. The resulting mixture was poured in 5 x 5 x 5 cm wooden molds, covered with plastic bags, and placed in an oven at 60 ⁰C for 24 hours. Finally, the cubes were left at room temperature (26±2 ⁰C) for 9, 16, and 27 days before the compressive strength testing.

Kaolin Mill For Petroleum Cracking Catalyst
To obtain an improved alyst for fluid cracking purposes, kaolin or metakaolin is reacted with an acid of the group of phosphoric, sulphuric and acetic acids by mixing and heating to 25110 C., after which the slurry is washed. The slurry is not neutralized prior to washing. The thus obtained kaolin is then mixed with a crystalline aluminosilie and, optionally, with a clay ( ...

Ball milling
A ball mill is simply a container that is filled with pebbles (either of porcelain or stones Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low speed ...

· In the author's lab, metakaolin was milled for 2 h (wet ball milling, a 75 mL/100 mL ethanol solution as the solvent, rotation speed of 400 rpm, and balltopowder ratio of 5 : 1). Then, the metakaolin solution was heated at 750 ± 10°C for 2 h for dehydroxylation. Dehydroxylation caused alumina and silica to become disordered.

Ball Milling method for synthesis of nanomaterials
1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.
