Hopefully a fun start to this topic and page:
recent happy successes videos and picture
Lead ingot smelted from our mineral concentrate of local ore.
Collecting thoughts - Significance : reference-feed=>mill=>particle-size-analysis .
Carn Brea Mining Society's "own" mine.
ex. Camborne School of Mines training mine and Holmans (the rock-drill
manufacturer) test mine.
First visit to Condurrow Mine, and my first time in a working/workable mine.
Upgrade skip loading mechanism for hauling ore to surface.
On skips - 254-page PDF - a report from 1977. Hilariously excessive for the tiny Condurrow mine.
Rock-drill section
Rock-splitting down the mine to clear levels of boulders
The jaw crusher in the mill.
Mid December 2023 into early 2024 : Blasting - learning path - info sources
Likely to prove a significant step-upwards for me:
Opening My Gold Mine!
.
A 15-part series of videos on YouTube.
It's very American in the best way (in my opinion).
The geology of Cornwall's mineral lodes and the gold lodes in
California is very similar (?) - igneous (magma) intrusion into
sedimentary rock. Hence relevance to me.
Reviewing solely pragmatic demonstrable Radon information - what is the evidence of Radon being harmful, or not.
Excellent finding : South Terras mine - good radiation reading
Found uranium lode giving some good readings
Dumped as mine "tailings", the iron-arsenic-sulphide mineral - ode to Arsenopyrite!
Learning about Minerals Processing - "the bible" - read
Barry Wills' book.
Now done

- the general topics.
"Contact" between granite and elvan - common but good looking example.
See the "rod-mill" project and "first mineral separation" already mentioned.
Preparation : practiced plotting sieve-analysis data .
First sieve-analysis of particle size distribution on one of my grinds in my rod-mill done! A joyous "first" - opening the way ahead to optimise mineral processing.
