Acute toxicity of drilling muds on litopenaeus vannamei (Boone, 1931) postlarvae
A cute toxicity of six drilling muds (water based and synthetic based) was evaluated using Litopenaeus
vannamei postlarvae to establish the 96 h median lethal concentration (LC50). The
Suspended Particulate Phase (SPP) ...
Mud Volcano Devils’ Woodyard Trinidad 346
(2010-03-31)
This is a close-up view of a mud volcano at the Devil’s Woodyard, Hindustan, near Princes Town, Trinidad, showing a soft mixture of earth at the centre of this cracked dry mud with two little conical, volcano-shapes behind ...
Cu(II) adsorption from aqueous solution using red mud activated by chemical and thermal treatment
(2016-03-01)
Brazil is the third-largest producer of aluminium, with the red mud generated during the extraction of aluminium from bauxite through the Bayer process. The red mud has been studied for use as an adsorbent for removing of ...
Adsorption of Ni(II), Pb(II) and Zn(II) on Ca(NO3)2-Neutralised Red Mud
(2017-01-01)
This study aimed to investigate a novel method of red mud neutralisation by Ca(NO3)2 (NRM), keeping its adsorption capacity in relation to natural red mud (RM) for Ni(II), Pb(II) and Zn(II). Results pointed out that the ...
Methodology for evaluation of mud rush risk in block caving mining
(Southern African institute mining metallurgy, 2017)
Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
Use of red mud activated at different temperatures as a low cost adsorbent of reactive dyeUso de lama vermelha ativada em diferentes temperaturas como um adsorvente de baixo custo de corante reativo
(2021-01-01)
Red mud, a waste product generated during alumina extraction from bauxite, could be used as a low-cost adsorbent. Here, the effect of thermal treatment on the adsorption of Reactive Blue 19 (RB19) dye by red mud was compared ...
