Zeolites are natural crystalline aluminosilicates. Structurally, zeolites are tectosilicates exhibiting an open three-dimensional structure containing cations needed This article describes the production of nanoparticles of Chilean natural zeolite, using three size reduction methods: Ball mill, microgrinding, and microfluidization. Morphological characterization of samples indicated an average diameter of 37.2 ± 15.8 nm of the zeolite particles.

Transformation of heulandite type natural zeolites into synthetic
Although natural zeolite is widely used because of its abundant reserves and low price (Nakhli et al., 2017), the exploitation of natural zeolite involves the crushing, grinding and sorting of mineral deposits, which is usually accompanied by energy consumption and the destruction of the ecological environment.In this paper, the method of filling natural rubber with zeolite as filler was mainly studied in the following two aspects: firstly, experiments selected organic amine surface modifier to modify natural zeolite and used infrared spectroscopy to analyze the interaction between the modifier and zeolite, and secondly, studying the application of Application of Organic Amine Modified Natural Zeolite in Filling

CONTROL OF NATURAL ZEOLITE PROPERTIES BY MECHANICAL
In the present paper a Hungarian natural zeolite was mechanically activated in stirred media mill for various residence times in distilled water, meanwhile the particle size di stribu-tion and the grinding energy were measured. Additionally, on-line tube rheometer was used to study the rheology of the suspen-sion during the grinding process.Batch wet grinding of zeolite was studied with emphasis on a kinetic study in a laboratory size steel ball mill of 200 mm diameter. The breakage parameters were determined by using the single sized feed fractions of − 850 + 600 µm, − 600 + 425 µm and − 425 + 300 µm for the zeolite samples.

A Review on Zeolite: Application, Synthesis and Effect of Synthesis
Zeolite synthesis involves artificial formation of crystals under reaction conditions similar to that of formation of natural zeolites. Synthesis methods are categorized as either hydrothermal, solvothermal or ionothermal. Irrespective of the method employed, zeolite can be synthesized via either of the three synthesis mechanisms, which are: Synthetic zeolites also show much higher adsorption capacity for heavy metal ions (eg. Cd 2+, Pb 2+, Zn 2+, Cu 2+, Ni 2+, Cr 3+) than the natural zeolites [ 44, 45 ].
