So, I would like to share this database with the community, which comes from one of the most important parts of a mining process a flotation plant The main goal is to use this data to predict how much impurity is in the ore concentrate.
Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.
Assessment work - The amount of work, specified by mining law, that must be performed each year in order to retain legal control of mining claims. Authorized capital - see capital stock. Autogenous grinding - The process of grinding ore in a rotating cylinder using large pieces of the ore instead of conventional steel balls or rods.
NiceHash is an open marketplace that connects sellers or miners of hashing power with buyers of hashing power. Buyers select the crypto-currency that they want to mine, a pool on which they want to mine, set the price that they are willing to pay for it, and place the order.
