Caracterização dos sedimentos arenosos de uma barra de areia na Foz do Rio Vila Nova

Abstract

Mining is one of mankind's oldest activities, which over time has shaped cultural landscapes, influencing the evolution of civilizations over time. Most ores, rocks, or minerals found in the Earth's crust require, for their use, some beneficiation to improve their physical properties and/or chemical characteristics. Ore treatment or beneficiation consists of the physical or physicochemical separation of valuable minerals from non-valuable ones (gangue) to obtain an enriched portion, called concentrate. In this context, this work consists of characterizing sand samples from a sandy formation existing at the Vila Nova River Mouth, located in the State of Amapá, between the municipalities of Mazagão and Santana; with the objective of investigating whether they have acceptable physical properties for the civil construction industry, using the sands already commercialized as a parameter to be compared, as well as the standards applied to the beneficiation of civil construction aggregates.
