2. MINERALOGY OF ALUMINIUM
 THE CHIEF INDUSTRIAL SOURCE OF ALUMINIUM
IS BAUXITE.
 ATTEMPTS HAVE BEEN MADE TO EXTRACT THE
METAL FROM
1. ANDALUSITE,
2. ANORTHOSITE,
3. ALUNITE,
4. CLAYS – WITH LITTLE SUCCESS.

3.  OTHER ALUMINIUM MINERALS ASSOCIATED
WITH BAUXITE ARE
1. DIASPORE,
2. BOCHMITE,
3. GIBBSITE .

4. MODE OF OCCURRENCE AND ORIGIN
 BAUXITE DEPOSITS OCCURS AS:
 BLANKET AT OR NEAR THE SURFACE,
 INTERSTRATIFIED BEDDED DEPOSITS LYING ON
EROSIONAL UNCONFORMITIES,
 POCKET DEPOSITS OR IRREGULAR MASSES IN
LIMESTONE OR DOLOMITE, AND
 TRANSPORTED DEPOSITS.

7. USES OF ALUMINIUM
ALUMINIUM IN
DIFFERENT FORMS
USES REMARKS
ALUMINIUM METAL HOUSE HOLD
UTENSILS,
WRAPING MATERIAL,
AEROPLANE
CONSTRUCTION.
IN FINDS MANIFOLD
USES DUE TO ITS
LIGHTNESS,
DURABILITY AND
ELECTICAL
CONDUCTIVITY.
ALUMINIUM ALLOYS ALLOYS WITH ZINC,
COPPER OR
MAGNESIUM ARE
IMPORTANT. THEY ARE
DURABLE AND
RESISTANT.
IT ALLOYS WITH MOST
METALS AND SOME
NON-METALS.

 CHALCOPYRITE CUFES2
 BORNITE CU5FES4
 CHALCOCITE CU2S
 COVELLIITE CUS
 ENARGITE CU3As S4
 CUPRITE CU2O
 MALACHITE CUCO3 CU(OH)2
 NATIVE COPPER CU

9. MODE OF OCCURRENCE AND
ORIGIN
 COPPER OCCURS IN A VARIETY OF WAYS:
 MAGMSTIC SEGREGATIOUS IN DISSEMINATED
FORMS IN VEINS AND LODES, IN CONTACT
METAMORPHIC DEPOSITS, IN BEDDED DEPOSITS.
 PORPHYRY COPPER DEPOSIYS IS MOSTLY
ASSOCIATED WITH STOCKS OR CHONOLITHS
INTRUSIONS OF MONZONITE.
