Abstract
Este diseño se basa en una mesa que, mediante la vibración o movimiento, separa partículas minerales micrométricas de diferente peso específico, este proceso no utiliza ningún reactivo químico contaminante para el medio ambiente, solo necesita agua (H2O), el cual puede ser reutilizada para otros procesos.
Esta mesa reemplaza el proceso que comúnmente se realiza hoy en día para la separación del oro, llamado platoneo, que consiste en utilizar un platón en forma de olla convexa, donde se coloca el material que contiene oro, junto con el mercurio (Hg), esto crea un gran impacto en el medio ambiente por sus emisiones de mercurio y al mismo tiempo efectos a la salud por el contacto directo del mercurio con la piel y por la contaminación del agua que produce arrojar el agua utilizada de este proceso al río.
Los propietarios de empresas mineras invierten mucho dinero en tecnología, pero esta no es lo suficientemente eficiente, ya que se utilizan muchos químicos muy tóxicos para el medio ambiente y además no obtienen todo el oro en su totalidad, porque parte del oro s e encuentra en micro partículas y éstas son arrastradas fácilmente con el agua que es vertida luego del proceso al río.
Abstract This design is based on a table that, through vibration or movement, separates micrometric mineral particles of different specific weights. This process does not use any chemical reagents that contaminate the environment, it only needs water (H2O), which can be reused for other purposes. This table replaces the process that is commonly carried out today for the separation of gold, called plating, which consists of using a dish in the shape of a convex pot, where the material containing gold is placed, along with mercury (Hg), This creates a great impact on the environment due to its mercury emissions and at the same time effects on health due to direct contact of mercury with the skin and due to water pollution caused by throwing the water used from this process into the river. The owners of mining companies invest a lot of money in technology, but it is not efficient enough, since many chemicals that are very toxic to the environment are used and they also do not obtain all the gold in its entirety, because part of the gold is found in micro . particles and these are easily carried away with the water that is poured into the river after the process.
