The Santee Cooper rig is mostly for dragging baits or keeping cut bait off the bottom. Not so much for keeping live bait from swimming off or around. A 10" live bait will not be slowed down by a float. I will put a photo of a rig I use with live bait a lot. The sinker size is often 8 to 16 oz just to keep them out of structure.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …
How kinetics fit into the overall picture of testing and characterizing a new ore through to plant scale performance and concentrate production is illustrated by the flotation performance influence diagram referred to as the flotation PID. Mineralogy measures liberation characteristics and any mineral to mineral and mineral to gangue associations.

A lifetime of support We offer solutions for the whole life cycle of your flotation plant, from installation and
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …
The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in …
I bought my used 2018 F60 PHEV with the upgraded HK system. kept looking into speaker and amp upgrade for the current setup and went with a BAV SOUND speaker setup and it's bight and day to an already good but underpowered audio system. I hope to get an amp upgrade 1 day but it's not available yet for this version of BMW/MINI.
The continuous development of the global economy has resulted in a high demand for copper production and high copper consumption [1], [2], and exploitation and effective use of copper oxide mineral resources have attracted attention [3].Copper oxide deposits evolve from shallow copper sulfide deposits after long-term oxidation, and they are widely and abundantly …
In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. Mining companies are investing in advanced sensors, data integration, and machine learning to gain deeper insights into their flotation processes. …

First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color.
