Bioleaching of Low Grade Uranium Ore of Saghand Mine
This study deals with bioleaching of the low grade uranium ore of Saghand mine in Iran using a mixed culture of mesophilic bacteria (Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferrooxidans). Experiments were carried out in shaking flask examining the effect of temperature, initial ferrous ion concentration, pulp density and particle size. Variations of ...
متن کاملAssessment of radiation dose around uranium mining complex, Jaduguda, India
Mining and ore processing activities are associated with changes in the surrounding environment and may pose a risk to human health, if adequate safety measures are not taken. The uranium ore generally varies worldwide between 0.03 – 3% U3O8, except for a few deposits where higher levels of uranium is reported. More than 95% of the ore is converted into waste material called “tailings”. Around ...
متن کاملLife-cycle impacts from novel thorium–uranium-fuelled nuclear energy systems
Electricity generated from nuclear power plants is generally associated with low emissions per kWh generated, an aspect that feeds into the wider debate surrounding nuclear power. This paper seeks to investigate how life-cycle emissions would be affected by including thorium in the nuclear fuel cycle, and in particular its inclusion in technologies that could prospectively operate open Th–U-bas...
متن کاملApplication of stochastic programming for iron ore quality control
Stockpiling and blending play a major role in maintaining the quantity and quality of the raw materials fed into processing plants, especially the cement, iron ore and steel making, and coal-fired power generation industries that usually require a much uniformed feed. Due to the variable nature of such materials, they even come from the same source and the produced ores or concentrates are seld...
متن کاملMonitoring and Evaluation of Water Consumption in the Gohar-Zamin Iron Ore Complex (Sirjan) using Shewhart Control Charts
Background & objectives: One of the biggest concerns about the increasing development of the mining industries, especially in the dry and tropical regions, is their high water consumption and, consequently, the serious threat to the local water resources as well as the impacts of these industrieschr('39') pollution on the environment and other downstream water resources. Therefore, it is necess...
