Therefore, the flotation products were sieved using a 106 μm and 20 μm Tyler sieves to accurately analyze the mineral composition. The MLA measurements were conducted using two modes (i.e., extended back-scattered electron (XBSE) mode and sparse phase liberation (SPL) mode).

Skeena Resources (DB:RXF)

At 88.3%, average silver recovery was higher than gold recovery, which could be due to an association with galena and its favourable liberation and flotation kinetics. Individual rock type models were developed that relate silver recovery to silver feed grades. The resulting LOM silver recoveries were somewhat improved over the PFS.

Finally, the thermomechanical process showed a preferential liberation of individual anode active particles and thus was considered the preferred upstream route for flotation. However, the thermal treatment oxidized Al foils, rendering them brittle and resulting in their distribution in all size fractions. Among the three, the thermomechanical black mass showed the highest

The sample was crushed, ground, and screened into five narrow size fractions: +500, -500+250, -250+125, -125+74, and -74 m Each size fraction was weighed and analysed for ash, then stored in plastic bags until required for flotation tests. Table II shows the particle size and ash distribution of the sample.

size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.

1 Froth Flotation – Fundamental Principles

flotation rate, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995).

The effect of particle size distribution on froth stability in

One of the key parameters in flotation is the particle size distribution of the feed and it has been 2 shown in several studies that the optimal size range for flotation is relatively narrow, approximately 20 – 150 m (Gaudin et al., 1942; Jameson et al., 2007).

Quantifying the removal of stabilizing thiolates from gold

Gold nanoparticles 10 nm in size are typically prepared using stabilizing agents, e.g. thiolates. Often standard recipes from literature are used to presumably remove these stabilisers to liberate the surface, e.g. for catalytic or electrocatalytic applications, however the success of these procedures is often not verified. In this work, thiolate-stabilised
