help with method for slow alkaline drip

[oro-del-sur]

I need to setup an alkaline drip for a 1 t/hr solids feed to a small CIP plant.  

What is the most practical method to do this considering the low solubility of hydrated lime (calcium hydroxide)? 

I was wanting to use a 55 gal plastic drum but realize 400-500 grams will reach saturation, not nearly enough concentration to achieve 10-11 pH in the Pachuca tanks using a slow drip feed.  

The chemicals will feed into a trommel that washes / screens tailings - a continuous operation, designed to run 24/7.

Thank you in advance!

Any linkage to PM's refining?

CIP = Carbon In Pulp

He is talking about a plant that is using cyanide to recover precious metals from one ton of ore per hour.

Thanks Goran, in this case what is the function of
Calcium hydroxide to such an extent?

 

[anachronism]

Is he using it as a pH control instead of Sodium Hydroxide?

I found this recommendation:
0.5% sodium cyanide and 0.05% calcium oxide
