Texto completo da fonteThe effect of wash water on metallurgical performance was tested with various streams from the Falconbridge Strathcona mill at laboratory and pilot and full plant scale, and with the secondary cleaner stage at the Eastmaque Kirkland Lake mill.
Results show that mechanical entrainment is the major means of gangue transport up to the slurry-froth interface. Transport into the froth is mostly hydraulic, although entrapment becomes dominant at low water recoveries. Free gangue recovery was closely related to slurry water recovery at all three scales. Wash water at an optimum superficial rate of 0.03 to 0.07 cm/s reduced entrainment by anywhere from 30 to 70%, typical values being around 50%.
Wash water can be further assisted by mechanical and ultrasonic vibration of the froth, difficult to achieve at plant scale, or with warm wash water, which becomes attractive if a waste heat source is available. A further rejection of 10 to 20% then becomes possible.
Distributor geometry was aimed at washing the entire froth surface at laboratory and pilot scale. It was observed that the recovery of hydrophobic minerals generally increased because the froth was stabilized. At plant scale, two perforated pipes close to the concentrate weir yielded the most reject. Froth stabilization was lost, and recoveries decreased.

Texto completo da fonteThe method and extent to which mineral slurries are conditioned have been shown to greatly affect flotation grades and recovery. Most of this work is very mineral specific and centres around one or two operating variables. One of the major obstacles to understanding the effects of such pretreatment more fully, and to developing a global understanding of conditioning, is the system specific nature of the procedures applied to each mineral, and the apparently conflicting results across a range of mineral types. This thesis sets out to define conditioning both broadly enough to encompass almost all aspects of conditioning, as well as specifically enough to be useful in the study of single mineral-collector systems. Having done this, a measure of the efficiency or effectiveness of conditioning is devised and used to evaluate the relative effects of variables of conditioning, as well as to gain some insight into the mechanisms affecting the results. The work is completed by relating these observations to expected results in industrial applications and their implications on plant procedures. Most forms of conditioning for flotation were found to fit into two basic categories, which if they both take place in the same process, follow one another sequentially. In this thesis, these were termed "primary" and "secondary" conditioning, and were defined as follows: Primary Conditioning relates to the physical preparation of the surface of the particles, including comminution, oxidation, acid leaching and bacterial pretreatment. Secondary Conditioning is the process whereby prepared particles are rendered hydrophobic or hydrophilic through mixing, control of the environment and contacting with reagents.

Texto completo da fonteThis study utilised laboratory-scale column flotation experiments to investigate froth stability, with respect to, water recovery and top-of-froth bubble burst rate. Tests were conducted at different froth heights, superficial air rates and depressant dosages in a 2 m high Plexiglass column, using a PGM bearing UG2 ore from the Bushveld Igneous Complex. Four concentrate and tailings samples were simultaneously collected and solids and water recoveries were determined. Assays of the concentrates were conducted to establish the amount of platinum, palladium and chromite that was recovered under each operating condition. Video footage of the top of the froth was recorded and was used to measure the top-of-froth bubble burst rate. The stability of the froth was analysed qualitatively by comparing the relationship between water recovery and the bubble burst rate at the different operating conditions. A key finding from this study was that the concentration of particles had a large effect on the stability of the froth. The maximum concentration of particles was obtained when the tests were conducted in the absence of depressant. Under these conditions it was established that the froth produced was so stable that increasing the air rate only showed minor changes in the stability of the froth phase. This stability has been attributed to the presence of hydrophobic gangue, which stabilised the froth phase by embedding between adjacent bubbles and preventing bubble coalescence. Conversely, when a high depressant dosage was used the froth became unstable such that no trends could be established when either air rate or froth height were altered. The instability of the froth has been attributed to the depression of the majority of the froth stabilising gangue, which resulted in increased bubble coalescence.

Texto completo da fonteTässä diplomityössä tutkittiin miten pH:n ja vaahdotusrikastuksessa käytettävien kemikaalien annostuksien säätämisen prosessiin aiheuttamat muutokset vaikuttavat vaahtopatjan eri osien sähkönjohtavuuteen vaahdotusrikastus prosessissa. Kokeellisessa osiossa mittaukset tehtiin Oulu Mining School:in jatkuvatoimisella minipilot -rikastamolla Oulun Yliopistolla maalis- ja toukokuussa 2015. Vaahdon sähkönjohtavuutta mitattiin Outotecin ERT:n (Electrical Resistance Tomography) perustuvalla testisauvalla. Sauva oli asennettu tilavuudeltaan nelilitraiseen vaahdotuskennoon, joka toimi kuparin rikastuspiirissä esivaahdotuskennona. Vaahdon kuplakokoa, väriä, stabiilisuutta ja nopeutta mitattiin Outotecin FrothSenseTM -kameralla. Prosessivirtojen kemialliset koostumukset mitattiin röntgenfluoresenssiin perustuvalla menetelmällä. Työssä selvitettiin kolmen eri vaahdotuksessa käytettävän kemikaalin ja pH:n vaikutusta vaahtopatjan sähkönjohtavuuteen: Dowfrothin (Testi 1), ksantaatin (Testi 2) ja sinkkisulfaatin (Testi 3) annostuksien sekä pH:n (Testi 4) vaikutus. Jokainen testi koostui kolmesta askelkokeesta, jossa mainitun muuttujan arvoa muutettiin muiden muuttujien arvojen pysyessä vakioina. Jokainen testi toistettiin kahdesti. Ennakko-oletus oli, että muutokset pH:hon ja reagenssien annostuksiin aiheuttavat muutoksia prosessinparametreihin kuten kuplakokoon, vaahdon paksuuteen, kemiallisiin koostumuksiin jne., jotka puolestaan vaikuttavat vaahdon sähkönjohtavuuteen. Vaahto jaettiin korkeussuunnassa kerroksiin, jotta mahdollisia eroja sähkönjohtavuuksien arvoissa ja niiden muutoksissa eri vaahdon osien välillä pystyttiin tarkastelemaan. Työn teoriaosuudessa esitellään mineraalien rikastuksen prosessiketju, alkaen jauhatuksesta ja päättyen vedenpoistoprosesseihin. Työssä käydään läpi myös vaahdotusrikastuksessa käytettäviä kemikaaleja sekä eri parametrien mittauksessa käytettäviä mittausmenetelmiä. Kokeellisesta osiosta saadut tulokset osoittavat, että pH:lla sekä vaahdotuksessa käytettävien kemikaalien annostuksien muutoksilla on vaikutusta vaahtopatjan sähkönjohtavuuteen. Erityisesti kuplakoolla ja vaahdon paksuudella oli selkeästi vaikutusta vaahdon sähkönjohtavuuteen. Lisäksi huomattiin, että paksussa vaahdossa sähkönjohtavuuden arvot ja niiden muutokset olivat erilaisia vaahdon eri kerroksissa. Ohuessa vaahdossa erot sähkönjohtavuuksien arvoissa ja muutoksissa vaahtokerrosten välillä olivat huomattavasti pienempiä
